I would like to know and understand how reader and writer work.
I use the following configuration:
<batch:chunk reader="myReader" writer="myWriter commit-interval="50" throttle-limit="3"
In this case i will have 4 threads to execute this step. Are myReader and myWriter executed in the same thread ?
In my myReader class i read data from a simple table.
Is it necessary to split the table or to partition it so each thread will get its own data range ?
Or it is done automatically with this configuration ?
Thanks a lot
