Hey,
We've seen a considerable increase in the number of dropped mutations after
a major upgrade from 1.2.18 to 2.0.10. I initially thought it was due to
the extra load incurred by upgradesstables, but the dropped mutations
continue even after all sstables are upgraded.

Be cautious enabling query tracing. Great tool for dev/testing/diagnosing etc..
- but it does persist data to the system_traces keyspace with a TTL of 24 hours
and will, as a consequence, consume resources.

As Jonathan said, it's better to activate query tracing client side. It'll
give you better flexibility of when to turn on off tracing and on which
table. Server-side tracing is global (all tables) and probabilistic, thus
may not give satisfactory level of debugging.
Programmatically it's pretty

The Cassandra team is pleased to announce the release of Apache Cassandra

your issue as well.
