Christine Poerschke commented on SOLR-5730:
-------------------------------------------
bq. ... did you first intend to introduce MPF ... adding {{<sortMerges>}} just
to immediately deprecate it seems odd ...
Yes, my preference would be to first introduce MPF with (say)
{{UpgradeIndexMergePolicyFactory}} as example and for there to never be that
"alongside" <sortMerges> attribute.
Thanks for mentioning about {{useCompoundFiles}} meanings. It would be good i
think to not carry over the {{fixUseCFMergePolicyInitArg}} logic into the MPF
code.
> make Lucene's SortingMergePolicy and EarlyTerminatingSortingCollector
