To cassandra's pioneers:
Dear cassandra's pioneer, is there a fast import data tool from oracle to
cassandra besides java-coding? I used copy from command to import oracle's date
to cassandra's timestamp, but cassandra's timestamp validating is too strict to

Hi Leo,
The overlapping SSTables are indeed the most probable cause as suggested by
Jeff.
Do you know if the tombstone compactions actually triggered? (did the
SSTables name change?)

output? It will display both their
Probably overlapping sstables

Hi everyone,
I'm struggling to understand how can I query TTL on the row in collection (
