I think you’re on the right track, but I wanted to clarify that parallelization is controlled by the ‘Pool Size’ setting, which is orthogonal to the reuse setting. If you enable reuse, with a pool size of 1, only one child execution will be started and documents will be sent to it in order. If you enable reuse, with a pool size greater than one, more than one child execution will be started and documents can be sent to any of the child executions.
Thanks for the valuable inputs.
So do you mean if I keep pool size as 1 then it will initiate one instance of the pipeline as per the input document and it will not allow even start another instance which is a different pipeline?
What my understanding was if I send 5 input documents, the document has the name of the pipeline to be executed out of which 2 documents have p1-pipeline and 3 has p2-pipeline. Here I would like both p1 and p2 to start running parallel but process their inputs in sequence.
so is this how it should it work? If not can you help me how can I enable such processing? I tried the below,
I am extracting documents from DB and after sorting them as per pipeline name and timestamp sending it to pipeline execute with “reuse” enabled,
here is what my pipeline execute will receive as input, and below is the configuration,
I get error in pipeline execute
