Subject [jira] [Commented] (CASSANDRA-6117) Avoid death-by-tombstone by default
Date Wed, 02 Oct 2013 15:36:42 GMT


Oleg Anastasyev commented on CASSANDRA-6117:

Guys, I see a lot of log messages like
 WARN [CompactionExecutor:158] SliceQueryFilter - Read 1 live and 1123 tombstoned cells (see
on compaction of normal CF. 
IMHO reading a lot of thombstones on compaction and GC them is normal and should not be warned
(nor failed with TombstoneOverwhelmingException)

> 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.
