海外TECH	DEV Community	The beginner guide to Spring Batch Processing- Part 1	https://dev.to/codeitout_/the-beginner-guide-to-spring-batch-processing-part-1-1n0m	The beginner guide to Spring Batch Processing Part Spring Batch is a Lightweight compressive batch framework which is used to perform ETL tasks on bulk of data easily E ExtractT TransformL LoadIt s not a scheduler but it is intended to work with scheduler It can be used to load data from file to database or read data from database process it to give a different output and store them in a separate database Basically it s for large datasets or high volume of data Let s dive into spring batch architecture It mainly has components Application ーIt contains batch jobs code written by developers APIS etc Batch Core ーIt contains the core classes needed to launch and control the batch job i e JobLauncher Job Step JobExecution etc Infrastructure ーIt contains readers and writers services which will be used by developers to code the batch job i e ItemReader ItemWriter ItemProcessor etc Batch Processing Strategies Normal processing in batch windowIt is for simple batch processors When application is updating the data no other batch jobs or online users should be able to access it This is the assumption Single commit can be done at the end of the batch job Concurrent batch Online ProcessingThis is used in cases where both the batch job and online users can use the data simultaneously But the online user should not lock the data Physical locking can be minimised by optimistic Locking and pessimistic locking approach Commit is done at the end of few transactions each Thus at a time only a small partition of data might not be available for other processes Optimistic lockingThe usecase is at a given point the probability that both app and online users are updating the data is very less Thus timestamp column is added into the table When starting the batch job it is noted down and while updating the data after processing it it checks the same timestamp in the where clause It updates the data only if both the timestamp match If the timestamp doesn t match it won t update the data eg UPDATE TABLE T SET C ABC WHERE TIMESTAMP Twhere T is timestamp which was read initially before starting the processing Pessimistic locking The usecase for it is when it s highly likely that both app and online users are updating data at the same time Physical logical locks need to be retrieved in these cases Separate lock column can be maintained where when one user access the data the lock is set true for the record and if some other user tries to access the same data at same time he she won t be able to access it because of the lock Parallel ProcessingIt refers to multiple batch jobs running in parallel Thus less time consumed It can t share the resources between each other jobs running in parallel Data partitioning can be an option here We can use multiple threads to process in parallel We can also use control table which contains details of all shared resource and mentions if it is being used by some other application Thus the same resource won t be processed multiple times Cons ーControl table can itself become a critical resource PartitioningIt allows multiple versions of a batch application to run concurrently Reduces elapsed time taken by long batch jobs Database data input data will be split which allows the application to work on each data set independently Partioning partioning the db not necessarily Application should be flexible enough to decide the number of partitions Automatic and user controlled config should can also be considered It depends on the application developer writing the code Here in this diagram you can see that the input in split into multiple parts and is given to the controller Thus these can run in parallel and the results are then merged to get the final output These are few partitioning approaches as well Fixed and even break up of record set where the input data will be split evenly thus each job batch will get same number of records Break up by a key column where the data will be split based on a column be it a date range or some id Break up by Views refers to breaking the record set into views Extract table to a flat file refers to extracting table records and exporting to a flat file based on size of file If you prefer watching video you can follow this link So now you know what to do If you found this useful you know what to do now Hit that ️button and follow me to get more articles and tutorials on your feed	2022-10-21 19:41:11
