[jira] [Updated] (SOLR-7787) Fork HyperLogLog and remove fastutil
dependency
[ https://issues.apache.org/jira/browse/SOLR-7787?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dawid Weiss updated SOLR-7787:
------------------------------
Summary: Fork HyperLogLog and remove fastutil dependency (was: Promote fastutil to first-order dependency, remove HPPC (?))
> Fork HyperLogLog and remove fastutil dependency
> -----------------------------------------------
>
> Key: SOLR-7787
> URL: https://issues.apache.org/jira/browse/SOLR-7787
> Project: Solr
> Issue Type: Task
> Reporter: Dawid Weiss
> Assignee: Dawid Weiss
> Priority: Trivial
> Fix For: 5.3, Trunk
>
>
> So fastutil is now part of Solr's distribution (because the stats component uses hyperloglog library, which in turn requires fastutil). There are a few classes that use HPPC but these could be rewritten to use fastutil, thus saving a few MBs of the distribution size.
> Going the other way would be more attractive size-wise (HPPC is ~1.1MB, fastutil is ~17MB) but we have no control over HLL's dependencies.
