MergeRecord not merging

avatar
Expert Contributor

Hello, I have a MergeRecord processor that is not merging despite my conditions (with the exception of bin age).

I have configured:

- 1 minimum record 

- 2000 maximum records 

- 1 MB minimum size 

- no size limit 

- 10 bins 

- 30 min max age

- bin packing strategy, no correlation attribute 

 

I have a 3 node cluster, and the queue before the MergeRecord processor has got millions of files before it that reach a couple Gigabytes in size.

I can see the processor keeps opening/closing tasks (by the thread count icon on it), but no files are getting merged and outputted, except for the bin age being reached. I believe all the minimum merge requirements are met, and even the max record limit should be reached, yet the processor isn't working as I understand. I would appreciate any help debugging why it is not merging as expecteded. 

 

If it is relevant, I use a json reader and parquet writer. 

 

Thanks,

Eyal.
