[jira] [Created] (SOLR-8856) Do not cache merges in the hdfs block cache.

Mark Miller created SOLR-8856:
---------------------------------

             Summary: Do not cache merges in the hdfs block cache.
                 Key: SOLR-8856
                 URL: https://issues.apache.org/jira/browse/SOLR-8856
             Project: Solr
          Issue Type: Improvement
            Reporter: Mark Miller
            Assignee: Mark Miller


Generally the block cache will not be large enough to contain the whole index and merges can thrash the cache for queries. Even if we still look in the cache, we should not populate it.
