             Summary: Make LINK splitMethod the default for SplitShardCmd
                 Key: SOLR-15119
                 URL: https://issues.apache.org/jira/browse/SOLR-15119
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
    Affects Versions: master (9.0)
            Reporter: Megan Carey


REWRITE splitMethod is still the default in SplitShardCmd [1], despite LINK being much faster. IndexSizeTrigger in branch_8x already uses LINK by default [2], and we have found LINK to be reliable and performant at scale. This work will just update the default in SplitShardCmd to make LINK the default overall.
