Partition and paralllel processing

[arun4]

Hi,

I am using Partition to split the records from the database and need to process the records parallelly.

Currently I am using SimplePartitioner to split the records.

I have 750 records and my grid size is 10, according to my grid size (10) my step also executes 10 times.

But each time all the 750 records are processed instead of only 75.

Could you please suggest as how to solve this problem, so that in one grid only 75 records should be processed.

And also, Could you please suggest as how to execute the partitioned records parallelly in spring batch

Thanks for your reply in advance

what does your partition handler?

There is a very good example in the samples that illustrates how to use this. It's called partitionJdbcJob and it uses a simple implementation that splits based on a column (ColumnRangePartitioner)
