[jira] [Commented] (CASSANDRA-15833) Unresolvable false digest
mismatch during upgrade due to CASSANDRA-10657
[ https://issues.apache.org/jira/browse/CASSANDRA-15833?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17189914#comment-17189914 ]

---------------------------------------------
+1
just one thing you can fix on commit, instead of the "see CASSANDRA-15833"-comments, it would be nice to have the explanation in the code instead of having to read a JIRA ticket to understand

> CASSANDRA-10657 introduced changes in how the ColumnFilter is interpreted. This results in digest mismatch when querying incomplete set of columns from a table with consistency that requires reaching instances running pre CASSANDRA-10657 from nodes that include CASSANDRA-10657 (it was introduced in Cassandra 3.4).
> The fix is to bring back the previous behaviour until there are no instances running pre CASSANDRA-10657 version.
