[jira] [Commented] (SOLR-7787) Fork HyperLogLog and remove fastutil
dependency
[ https://issues.apache.org/jira/browse/SOLR-7787?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14626656#comment-14626656 ]
Hoss Man commented on SOLR-7787:
--------------------------------
I don't have any strong opinions about this issue as it currently stands (ie: "Fork HyperLogLog and remove fastutil dependency") -- as you mentioned, the java-hll project, with it's original goals of a cross langauge binary format protocol, doesn't appear to be very active anymore -- but for the record can you please clarify the context/objective of this issue?
It started out as "Promote fastutil to first-order dependency" -- and your goal seemed to be to remove HPPC, now you seem to have flipped the objective so that the focus is on keeping HPPC, and eliminating fastutil.
having a clear understanding of "the goal" for either refactoring/forking/etc would be helpful for folks to develop an informed opinion.

> So fastutil is now part of Solr's distribution (because the stats component uses hyperloglog library, which in turn requires fastutil). I looked at the actual uses of fastutil and only java-hll uses it (and only a few classes).
> I've created a fork that uses HPPC instead (also randomized all tests, they pass). Since it's a relatively simple package I think it could be forked and imported into Solr's codebase entirely. I'd make a pull request but I see Hoss also created a few comments/ PRs and none of them received any attention; the project seems to be stale or dead?
