- - &gt;&nbsp;ETL project phases There are 3 phases Phase &ndash; I
<h3>Data profiling</h3>
&nbsp;
<ul>
<li>Source System Analyses is done in this phase</li>
<li>There are 5 Types of Analysis</li>
</ul>
<ul>
<li>Ca - - &gt;&nbsp;&nbsp;Column Analysis</li>
<li>Pa - - &gt;&nbsp;&nbsp;&nbsp;primary key Analysis</li>
<li>Fa - - &gt;&nbsp;&nbsp;foreign key Analysis</li>
<li>Bl - - &gt;&nbsp;&nbsp;&nbsp;base line Analysis</li>
<li>Cd - - &gt;&nbsp;&nbsp;&nbsp;cross domain Analysis</li>
</ul>
<ul>
<li>The output we get is whether the data is Directly or Not.</li>
<li>If the data is dirty proceed to next phase</li>
</ul>
Phase &ndash; II
<h3>Data Quality or cleansing</h3>
<ul>
<li>There are 5 Stages</li>
</ul>
<ol>
<li>Parsing</li>
<li>Cording</li>
<li>Standardize</li>
<li>Matching</li>
<li>Consolidate</li>
</ol>

 Example
EXP _ EMP &agrave; hire date &agrave; EMP
Dept Name &agrave; DNO &agrave;DEFT
First Name
Last Name
Middle Name.
- - &gt;&nbsp;&nbsp;from these 5 details a Mapping document is text prepared and given to the developer
Exp _ EMP :-
To find out the experience of an employee we need to&nbsp; know the hire date&nbsp; from the EMP table
So, EMP is one of the Source entity, and its Source attributes will be ENO, ENAME, Hire date, DNO .
DEPT Name :-
To Know the Dept Name, We need to Know the DNO from DEPT table
So, DEPT is another Source Entity with DNO, DANME as Source attributes.
- - &gt;first, last and Middle Names Will be taken from the EName of EMP Table.
- - &gt; Now the Target Attribute, that we need to find out are, ENO, First Name, Middle Name, Last Name, EXP_EMP, Dname
Target Entity or Target&nbsp; Table Will be EXP_ EMP Conventions:-
Set of rules to be followed
There are 4 types of conventions that are to be followed while naming :
-Job Naming
-Stage Naming
-Variable Naming
-Parameters Naming

<ul style="text-align: justify;">
<li>Transformations may take place in different ways from Source to target.</li>
</ul>
- - &gt;&nbsp;We may load the Source attribute ENO as it is to the Target &nbsp;Attribute , or may make Same &nbsp;&nbsp;attribute.
<h2 style="text-align: justify;">Attributes</h2>
The data-* attributes is used to store custom data private to the page or application.
The data-* attributes gives us the ability to embed custom data attributes on all HTML elements.
The stored (custom) data can then be used in the page's JavaScript to create a more engaging user experience (without any Ajax calls or server-side database queries).
The data-* attributes consist of two parts:
-The attribute name should not contain any uppercase letters, and must be at least one character long after the prefix "data-"
-The attribute value can be any string
Note: Custom attributes prefixed with "data-" will be completely ignored by the user agent.
Ex: We have ENO as N 1234, N 3567
-The transformation we need to make is change All Ns to the value 8.
-Now, ENO Will be 81234,83563
-Both the source entities may have on <a class="zem_slink" title="Referential integrity" href="http://en.wikipedia.org/wiki/Referential_integrity" target="_blank" rel="noopener wikipedia">Referential Integrity</a> i.e they are related With each other to make same transformations.

-Designing
-Performance
-Testing

<h4>Conversion takes place , when we use Sequential file stage for staging the data</h4>
&nbsp;
<ul>
<li>A stage is an operator prebuilt in component</li>
<li>Sequential file is associated with import and export operators</li>
</ul>
<img class="alignnone wp-image-6985" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2014/12/Screenshot_44-460x429.png" alt="Screenshot_44" width="451" height="419" /> &nbsp;
<h4>&nbsp;Data lands outside the Data stage</h4>

Filter's & Data Set in Data Stage

filters-data-stage

To overcome the limitations of sequential file, we use Data set
<ol>
<li>Data set is a parallel processing Stage which is used for staging the data, when we design dependent jobs</li>
</ol>
(That is Transformation jobs are dependent on extraction jobs.&nbsp;&nbsp;And loading jobs are dependent on Transformation jobs ).
<ol start="2">
<li>Data set can accommodate more than 2 GB</li>
<li>Data set stores data in Native format, so no conversion is required</li>
<li>Data lands inside the data stage repository</li>
</ol>
<h3>Types of Data Set</h3>
Virtual :-&nbsp; Data moving through the link is virtual, (temporary) Persistent :- Data &nbsp;created with Data set is persistent,&nbsp; (permanent) In target file,&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; C: /data/output. DS &agrave;persistent &agrave;permanent
<h3>Alias of Data set</h3>
<ol>
<li>Orchestrate file</li>
<li>Operating System file</li>
</ol>
<h3>Data set files</h3>
Data set is not a single file, but has multiple files
<ul>
<li>Descriptor file</li>
<li>Data file</li>
<li>Control file</li>
<li>header file</li>
</ul>
<ol>
<li>Descriptor file : -</li>
</ol>
Schema details and address of data &agrave; Structure () table definition C:/data/file. ds
<ol start="2">
<li>Data file :-</li>
</ol>
Contains data in Native format C:/IBM/Information Server / Server/data set/ file. Ds
<ol start="3">
<li>Control file (or) header file :-</li>
</ol>
Resides in operating system.
<h3>How to create and recues Data set</h3>
Extraction: <img class="alignnone wp-image-6988" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2014/12/Screenshot_45-460x117.png" alt="Screenshot_45" width="403" height="102" />
<ul>
<li>After compiling &agrave; Run</li>
<li>Now, copy the Target file path that is .ds file path</li>
<li>Go to columns&agrave;Save&agrave;Table Definer&agrave;Ok&agrave;Select the file&agrave;Ok</li>
</ul>
Transformation <img class="alignnone size-full wp-image-6989" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2014/12/Screenshot_46.png" alt="Screenshot_46" width="188" height="101" /> &nbsp; Here are&nbsp;properties&nbsp; Paste the Extraction Target path<img class="alignnone size-full wp-image-6279" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2014/12/712.png" alt="7" width="55" height="13" />Columns &agrave;Load
<ul>
<li>Data is the Extraction Target gets into Transformation Data set.</li>
</ul>
To view Data set outside the job&nbsp;
<ul>
<li>Data set cannot be directly copied or deleted because, it has multiple files</li>
</ul>
<ul>
<li>Organize Data set :- (View, copy, delete)</li>
</ul>
<ul>
<li>We use Data set utilities for organizing Data.</li>
</ul>

Container in DataStage

container-data-stage

<h2>Miscellaneous Stage</h2>
Staging area &ndash; Retains data from 7 days to 1m other.
<h3> Compress And Expand </h3>
Both are interdependent stages
Used for doing Data Backup
<h3>Compress Stage&nbsp; </h3>
Compress the data using COMPESS&nbsp;&nbsp; (or) GZIP Commands.
&nbsp; <img class="alignnone wp-image-7144" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2014/12/Screenshot_88-460x127.png" alt="Compress stage" width="454" height="124" /> &nbsp;

<h3>Expand Stage </h3>
Expand the Compressed data using UNCOMPRESS or GUNZIP.
&nbsp; &nbsp;<img class="alignnone wp-image-7145" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2014/12/Screenshot_90-460x90.png" alt="Expand Stage" width="471" height="91" />
<h3>Encode and Decode&nbsp; </h3>
Encrypts and Compresses

<h2 style="text-align: justify;">Job Sequencing</h2>
It is Controlling the order of execution.
Master Job
Can run multiple jobs with the same name
<img class="alignnone wp-image-7152" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2014/12/Screenshot_931-460x204.png" alt="Screenshot_93" width="426" height="189" />
Trigger&nbsp;
Checking the compilation of job 1,&nbsp; if it is compiled without errors, then job 2 is compiled.
Error handling&nbsp;
This situation arises when Job is Aborted
Notification
When everything is successful, we should get a confirmation mail that it is Successful.
Wait for file&nbsp;
Waits for the file, until it is searched and gets loaded into the source.
Checkpoints
If a job is aborted in between by any chance, check point make sure that the job starts from the point where it has failed.
Parameter Mapping&nbsp;
We cannot use a parameter defined in 1 job to another job, TO do this we use parameter Mapping.
Job sequencing Stages are categorized into 4 groups&nbsp;
<ol style="text-align: justify;">
<li>Run stages</li>
<li>Flow control stages</li>
<li>Error handling stages</li>
<li>Other stages</li>

Job Sequencing in Data Stage

<h2 style="text-align: justify;">Partitioning Technique With Performance Tuning</h2>
Partitioning is the process of dividing an input data set into multiple segments, or partitions. Each processing node in your system then performs an operation on an individual partition of the data set rather than on the entire data set.
&nbsp;
<h2>Data Stage basically allows 2 types of partitioning</h2>
<ul>
<li style="text-align: justify;"><a href="#key-based-technique">Key Based Partitioning</a></li>
<li style="text-align: justify;"><a style="color: #236fa1;" href="#keyless-techniques">Keyless Partitioning</a></li>

<h4>Hash</h4>
Rows with the same key column (or multiple columns) go to the same partition. <a title="Hash Maps in TeraData" href="https://tekslate.com/hash-map-teradata/" target="_blank" rel="noopener">Hash</a> is very often used and sometimes improves performance, however it is important to have in mind that hash partitioning does not guarantee load balance and misuse may lead to skew data and poor performance.
<h4>Modulus</h4>
Data is partitioned&nbsp;on one specified numeric field by calculating modulus against the number of partitions. Not used very often.
<h4>Range</h4>
An expensive refinement to hash partitioning. It is similar to hash but partition mapping is user-determined and partitions are ordered. Rows are distributed according to the values in one or more key fields, using a range map (the 'Write Range Map' stage needs to be used to create it). Range partitioning requires processing the data twice which makes it hard to find a reason for using it.
&nbsp;
<h3 style="text-align: justify;"><a id="keyless-techniques"></a>Keyless Techniques</h3>
<ul>
<li style="text-align: justify;">Same</li>
<li style="text-align: justify;">Entire</li>
<li style="text-align: justify;">Round Robin</li>
<li style="text-align: justify;">Random</li>
</ul>
<h4>Entire</h4>
All rows from a dataset are distributed to each partition. Duplicated rows are stored and the data volume is significantly increased.
<h4>Same</h4>
Existing partitioning remains unchanged. No data is moved between nodes.
<h4>Round robin</h4>
Rows are alternated evenly across partitions. This partitioning method guarantees an exact load balance (the same number of rows processed) between nodes and is very fast.
<h4>Random</h4>
Rows are randomly distributed across partitions
All key-based stages, by default, are associated with Hash as a Key-based Technique.
<h3>Hash Technique</h3>
Hash Partitioning is one of the most popular and frequently used techniques in the Data Stage. Under this part, we send data with the Same Key Colum to the same partition.
Example
<img class="aligncenter wp-image-7159" title="Partitioning Technique in DataStage-Hash Technique" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2014/12/Screenshot_97-460x219.png" alt="Partitioning Technique in DataStage" width="486" height="230" />
Same Key Column Values are Given to the Same Node.
Hash partitioning Technique can be Selected into 2 cases
<ul style="text-align: justify;">
<ul style="text-align: justify;">
<li>If Key Column &gt; 1</li>
<li>If key column = 1, other than Integer</li>
</ul>
</ul>

<h3 style="text-align: left;">&nbsp;Why Modulus?</h3>
<ul style="text-align: justify;">
<li>Modules are having good performance when compared to the hash.</li>
<li>In modules, it distributes the data by calculating MOC Value</li>
</ul>
<a href="https://tekslate.com/tutorials/datastage-tutorials/"><img class="aligncenter wp-image-7160 size-full" title="DataStage Tutorials-Partitioning Technique" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2014/12/Screenshot_98.png" alt="MOD" width="263" height="215" /></a>
Note:&nbsp;Modules is Having Good performance than Hash
MOD is selected, when it has only 1 key column, and it is an integer.
Join <img class="alignnone size-full wp-image-7108" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2014/12/1111.png" alt="11" width="37" height="12" />&nbsp;Dept no, E no
We use Hash,&nbsp; As key column &gt; 1
That is dept no, E no (we have 2 key column values)
<img class="aligncenter wp-image-7161" title="DataStage tutorials-Partitioning Technique in DataStage" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2014/12/Screenshot_99-460x227.png" alt="Partitioning Technique in DataStage" width="438" height="216" />
because, we want the same distribution from joining to Aggregator, and key column value is also the same, so we use SAM <img class="alignnone size-full wp-image-7108" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2014/12/1111.png" alt="11" width="37" height="12" />&nbsp;SAME is Key less
<img class="aligncenter wp-image-7162 size-full" title="DataStage tutorials-Partitioning Technique in DataStage" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2014/12/Screenshot_100.png" alt="Partitioning Technique" width="386" height="213" />
We cant use SAME, here, as join has 2 key column values D no, loc, if we use SAME, We don&rsquo;t Know that what data is getting from joining to Aggregator.
Modulus &agrave; because of only 1 key column (D NO) and Integer.

<h3>Reasons&nbsp; for Dirty data</h3>
<ol>
<li>lock of information Standards</li>
<li>1 field is used for Multiple</li>
</ol>
Data in a data base is after misplaced. Data Redundancy Data is required in to Systems, because the data entry mechanism is not aware that the original&nbsp; record is already there. To perform Data Quality , we have 4 stages :- &nbsp; <img class="alignnone wp-image-7172" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2014/12/Screenshot_105-460x163.png" alt="Screenshot_105" width="481" height="170" /> &nbsp; &nbsp;

In general, we have 4 &nbsp;Architecture
<ul>
<li>Simple</li>
<li>ODS&nbsp; - Operations Data source</li>
<li>NDS &ndash; Normal&nbsp; Data source</li>
<li>Integrity &nbsp;</li>
</ul>
<img class="alignnone size-full wp-image-7108" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2014/12/1111.png" alt="11" width="37" height="12" /> we can implement this Architecture either in Inmon Model or Kimball Model
Top to bottom&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Bottom to top

Universally&nbsp; -&nbsp;&nbsp; 8 Architecture
Inmon &ndash; Simple, ODS,&nbsp; NDS, Integrity
Kimbell - Simple, ODS,&nbsp; NDS, Integrity.
<h3>Simple</h3>
SRC ---- WH
<img class="alignnone size-full wp-image-7181" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2014/12/Screenshot_1111.png" alt="Simple Architecture" width="153" height="142" />
<h3>&nbsp;ODS</h3>
<img class="alignnone size-full wp-image-7184" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2014/12/Screenshot_1121.png" alt="ODS Architecture" width="354" height="205" /> &nbsp;
<ul>
<li>Inmon Models are preferred when Requirements are very clear.</li>
<li>Kim bell Model is preferred when&nbsp;&nbsp; Requirements are not clear. &nbsp;</li>
<li>For the project, we deal with</li>
</ul>
<ol>
<li>ODS --&agrave;80% ODS Model</li>
<li>NDS</li>
</ol>
<h3>WHY ODS?</h3>
Sol:- when&nbsp; Business Requirements are defined, click/customer requests the team&nbsp; what we want exactly
. &nbsp; <img class="alignnone wp-image-7185" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2014/12/Screenshot_1131-460x406.png" alt="ODS" width="388" height="341" /> &nbsp;

<ul>
<li>More priority is given to operational and Analysis Reports</li>
<li>Are we have more operational Reports we use ODS.</li>
<li>Less operational Reports and more Analytical Reports, we use NDS.</li>
<li>In NDS, we can&rsquo;t See ODS, But in ODS, we can find warehouse and Data marts (NDS).</li>
<li>ODS gets refreshed every 10 seconds.</li>
<li>ODS dim Table will always be type 1 (No History)</li>
</ul>

<li>Hash</li>
<li>Modulus</li>
<li>DB2</li>
</ul>
<h3 style="text-align: justify;">Hash</h3>
Determines partition based on key-value(s). One or more keys with different data types are supported.
Example: Key is State. All &ldquo;CA&rdquo; rows go into one partition; all &ldquo;MA&rdquo; rows go into one partition. Two rows of the same state never go into different partitions.
<h3 style="text-align: justify;">Modulus</h3>
Partition based on the modulus of key divided by the number of partitions. The Key is an Integer type.
Example: Key is OrderNumber (Integer type). Rows with the same order number will all go into the same partition.
<h3 style="text-align: justify;">DB2</h3>
Matches DB2 EEE partitioning
Example: This partition is used when loading data into the DB2 table. It takes the partition key from the loading DB2 table and inserts the records effectively. If the partition key is defined in the DB2 database then it takes that Partition key otherwise it defaults to the primary key.
This figure gives a clear view of Key-based Partitioning and repartitioning.

Ascential parallel technology operates by a divide-and-conquer technique, splitting the largest integration jobs into subsets ("partition parallelism") and flowing these subsets concurrently across all available processors ("pipeline parallelism"). This combination of pipeline and partition parallelism delivers true linear scalability (defined as an increase in performance proportional to the number of processors) and makes hardware the only mitigating factor to performance. However, downstream processes may need data partitioned differently. Consider a transformation that is based on customer last name, but the enriching needs to occur on zip code - for house-holding purposes - with loading into the warehouse based on customer credit card number (more on parallel database interfaces below). With dynamic data re-partitioning, data is re-partitioned on-the-fly between processes - without landing the data to disk-based on the downstream process data partitioning needs.

<li style="text-align: justify;">Round Robin</li>
<li style="text-align: justify;">Entire</li>
<li style="text-align: justify;">Same</li>
</ul>
<h3 style="text-align: justify;">Round Robin</h3>
The first record goes to the first processing node, the second to the second processing node, and so on. When DataStage reaches the last processing node in the system, it starts over. This method is useful for resizing partitions of an input data set that are not equal in size. The round-robin method always creates approximately equal-sized partitions. This method is the one normally used when DataStage initially partitions data.
Example: Assume 8 nodes are allocated to store the records then 1st record will go into the first node and the 2nd record will go into the second node &hellip;&hellip;8th record will go into the eighth node and the 9th record will go into the first node and so on&hellip;.
<h3 style="text-align: justify;">Entire</h3>
Send all rows down all partitions
Example: Assume 8 nodes are allocated, then in all the 8 nodes all the records will be passed.
<h3 style="text-align: justify;">Same</h3>
Preserve the same partitioning.
Example: Two stages in a job (Sort and Dataset). In the sort stage, you have done &ldquo;Hash&rdquo; partition and in the dataset, you have given the &ldquo;Same&rdquo; partition. In the dataset, the data will be preserved with the hash partition.

<h2 style="text-align: justify;">Appropriate Ways</h2>
<h3 style="text-align: justify;">Step 1: (Serial extraction with proper partition)</h3>
In this job, extraction is made serial in both the DB2 stages. All the records will reside in 1 partition. As input link1 of the Sort stage has been &ldquo;hash&rdquo; partitioned, 1 partition will split into 8 partitions based on the given key(s), and records are also sorted based on the joining key(s). In the Join stage for link2, the &ldquo;same&rdquo; partition is given, and on the other side for link3 with the same key(s) &ldquo;hash&rdquo; partition and internal sorting is done so that records from 1 partition will split into 8 partitions and also sorted within the partition. Now joining will be done effectively and the records are captured in the dataset with the &ldquo;same&rdquo; partition, which will maintain the records in 8 partitions. For 1 partition, 1 page will be created. So, for the entire job, 32 pages will be created.
<img class=" wp-image-20287 aligncenter" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2016/05/Capture.845.png" alt="Serial extraction" width="626" height="163" />
<h4 style="text-align: justify;">Suggestion:</h4>
This will be one of the best ways to design the job for a huge volume of data. But, extracting the records in serial makes performance to go down. Multiple instances can be enabled in this job and can be called in parallel to attain parallelism.
<h3 style="text-align: justify;">Step 2: (Parallel extraction with proper partition)</h3>
This job is the same as the previous job but extraction alone made in parallel. In extracting the records in the DB2 side, 64 partitions will be created.
<img class=" wp-image-20288 aligncenter" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2016/05/Capture.846.png" alt="Parallel extraction" width="637" height="252" />
<h4 style="text-align: justify;">Suggestion:</h4>
This will be one of the best ways to design jobs for a huge volume of data. But, the number of database connections been established is huge.
<h4 style="text-align: justify;">Step 1:</h4>
As the extraction is done in a serial mode in both the DB2 stages, the allocated node will be 1 that is all the records will be in one partition and in all the remaining stages have the &ldquo;same&rdquo; partition, so the number of partition is retained as 1 in all the stages. So, the page created for this job will be 4.
<img class=" wp-image-20289 aligncenter" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2016/05/Capture.847.png" alt="step 1" width="675" height="234" />
Suggestion:
This job will work fine for the low records. But for the huge records, it will hang. Since the entire job is in serial mode.
<h4 style="text-align: justify;">Step 2:</h4>
Here the extraction is made parallel in both the DB2 stages. So, the allocated node will be 64 and in all the other stage the partition are &ldquo;same&rdquo; so for every stage the allocated node will be 64. So the page created for this job will be 256.
<img class=" wp-image-20290 aligncenter" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2016/05/Capture.848.png" alt="Step 2" width="626" height="209" />
Suggestion:
For less or huge records this job will work very fast but it will occupy maximum space in the system. For this job wastage of memory (Paging Issue may come up) happens because 256 pages will be created and sometimes this kind of job will make the entire system to come down.
<h4 style="text-align: justify;">Step 3:</h4>
An unpredictable thing may happen here because it all depends on the stages it will decide on its own since it is an auto partition.<img class=" wp-image-20293 aligncenter" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2016/05/Capture.849.png" alt="Step 3" width="635" height="261" />
Suggestion
Never use auto partition in the job.
<h4 style="text-align: justify;">Step 4:</h4>
In this case performance wise no issues but will lose the data on the Join stage because on the Link2 it is coming as 8 nodes and on the other side Link3 in 64 nodes so DataStage cannot join the data accurately since Join Stage is depended on the master link. In this case, Link2 is the master link so it will join only with the 8 nodes and it will leave the other 56 nodes which is coming from the Link3. Therefore data coming from that 56 nodes will not be considered.
<img class=" wp-image-20294 aligncenter" src="https://newtekslateassets.s3.us-west-2.amazonaws.com/wp-content/uploads/2016/05/Capture.850.png" alt="Step 4" width="644" height="257" />
Suggestion:
Never join the link without having the same partitioning key on both sides otherwise data loss may occur and also sort the records before joining.
