Process source Opensearch index just once and stop - is there a way for such behaviour ?

[tzaleski-vertexinc]

Hi,

I've set up a pipeline to copy indices from Opensearch on prem to AWS Opensearch Serverless. The sink uses time series collection which means that one can't index by custom document id.
With just one index set to be included from the source when the pipeline is started PitWorker processes the index, the data is copied but after a while PitWorker starts processing the same index and the data is being copied again (and this happens again and again...). The outcome is that the "new" index has n times more documents than the source index. Is there a way to stop processing indices after the first time?

I've tried setting on the source

            scheduling:
                index_read_count: '1'

or

            scheduling:
                index_read_count: '1'
                interval: P365D

but the source index has been processed twice.

Thx in advance,
