I sent bluk to elasticsearch via Nifi using PutElasticsearch5 processor.
In the Nifi processor code:
When sent to elastic sesrch using transport client, i got an array of responses for each in the bulk.
I checked if there was a problem, using elastic client libraries:
For every bulk we got a successful response ( BulkResponce class) for each doc in bulk.
Then, i encountered a problem:
When accessed to the index in ES, i noticed that there was some missing docs (about 0.7%)
I checked the logs in the ES environment and didn't see anything that indicates loss of data in the index.
The elastic env was stable during the insert, and also the Nifi environment.
Any idea what could cause this situation?
