Thank you for the additional options Jörg

There are more alternatives:

"sliding window" - organize index names to create incremental indexing
each 15 minutes. By selecting the index name by timestamp, you do not need
to dump anything for getting a subset.

"versioning" - use explicit versioning for detecting modifications.
Versions are long values, so they could also represent timestamps. With
scan/scroll, examine document versions if they match a criteria for being
"new". This approach does not scale well with index size.

"logging" - another method would be to add logging statements, maybe near
the translog, collect the logs and process them externally. This requires a
few additional code to the ES core. Collecting logs may be tedious.
