{{DecoratedKey}} is really two parts: {{Token token, ByteBuffer key}}
The {{token}} is a hash of the {{key}}, and we write sorted by {{token}} (not
by {{key}}).
Those of you hitting this bug, can you please post:
- What version of cassandra you're using
- Schema of the impacted table (anonymize column names if needed)
- What memtable settings you're using (onheap, offheap)
