[jira] [Commented] (CASSANDRA-8793) Avoid memory allocation when searching index summary

    [ https://issues.apache.org/jira/browse/CASSANDRA-8793?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14345156#comment-14345156 ] 

Benedict commented on CASSANDRA-8793:
-------------------------------------

Updated repo with those changes. As to other callers, getKeySamples() is the only example I can see, and it is called rarely. It would require some (slight) ugliness inducing refactor which is probably not worth the low yield IMO.
