[jira] [Updated] (CASSANDRA-6117) Avoid death-by-tombstone by default

     [ https://issues.apache.org/jira/browse/CASSANDRA-6117?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jonathan Ellis updated CASSANDRA-6117:
--------------------------------------

    Attachment: 6117.txt

The main tricky point is that SQF is also used for PrecompactedRow.  Added an opt-out method for IQF subclassing it.

> We added warnings to 1.2 (CASSANDRA-6042); for 2.0 we should go farther and drop requests (with an error logged) that exceed the threshold.  Users who want to tread dangerously are free to crank the threshold up, but "I queried a lot of tombstones and Cassandra fell over" is possibly the number one way of killing Cassandra nodes right now.
