Evan Prothro commented on CASSANDRA-12336:
------------------------------------------
Currently we're working around this by effectively disabling compaction with an
extremely high value for `gc_grace_seconds` on tables with static fields.
Clearly the shorter we have to live with that workaround the less nervous we
are.
Please don't hesitate to let us know anything we can do to help isolate or
reproduce. We can provide an sstable and schema that should reproduce.
