Tommaso Teofili commented on OAK-6514:
--------------------------------------
sure, thanks Thomas for reminding me :)
So you can set the merge policy by setting a "mergePolicy" property on the
index definition, valid values are:
* default / mitigated : the {{CommitMitigatingTieredMergePolicy}} developed as
part of OAK-5192
* no : no merge policy
* tiered : Lucene's default {{TieredMergePolicy}}
* logbyte : Lucene's {{LogByteMergePolicy}}
* logdoc : Lucenes' {{LogDocMergePolicy}}
If nothing is set, {{CommitMitigatingTieredMergePolicy}} is used.
> Make Lucene merge policy configurable

> To test OAK-5192, it would be good if the merge policy (how often to merge)

> Depending on test results, we might want to change the default settings.
