Re: Slow soft-commit
almost forgot to report back, maybe it helps somebody else .... it turned
out to be caused by a feature in our software being used in a way we did
not anticipate.
That resulted in a lot (> 100.000) of different dynamic fields which
probably is an anti-pattern on its own, but the slow commits where related
to the fact that these fields had DocValues. After some profiling, it
clearly showed a lot of time was spent in FieldInfos' addOrUpdateInternal()
and related code.

Re: Slow soft-commit
Posted by Erick Erickson <er...@gmail.com>.
Thanks for letting us know. Yeah, many thousands of fields is an anti-pattern. At some point I’d like to put in a limit or log warning or something so people would get warning when something like this happens.
And to make matters more “interesting”, the meta-data associated with the fields doesn’t go away.. ever. You need to re-index to a new collection.
Certainly the soft commits should be much faster if you re-index without using a new collection, but there’s still some inefficiencies in the meta-data being kept.
Best,
Erick

Re: Slow soft-commit
Posted by Erick Erickson <er...@gmail.com>.
Thanks for letting us know. Yeah, many thousands of fields is an anti-pattern. At some point I’d like to put in a limit or log warning or something so people would get warning when something like this happens.
And to make matters more “interesting”, the meta-data associated with the fields doesn’t go away.. ever. You need to re-index to a new collection.
Certainly the soft commits should be much faster if you re-index without using a new collection, but there’s still some inefficiencies in the meta-data being kept.
Best,
Erick
