Is this a LCS family, or Size Tiered? Manually running compaction on LCS
doesn't do anything until C* 2.2 (
https://issues.apache.org/jira/browse/CASSANDRA-7272)
Thanks,

Hello,
I need to have a table that is acting as a queue for specific data. Data
that has to be stored in this table are some unique ids that have to be
predefined and whenever it is requested one id has to be obtained by the

Hi all,
I am trying to troubleshoot a case in which the jsvc process (in which
Cassandra is running) uses more and more memory until the OS kills the
process and so Cassandra is restarted.
OS: Ubuntu 12.04
Java: Oracle JDK 8u45
Cassandra: 1.2.19 (datastax)
*Note: We are currently tied to Cassand

Hello,
Daniel, I am using Size Tiered compaction.
My concern is that as I do not have a TTL defined on the Column family, and
I do not have the possibility to create it. Perhaps, the "deleted data"
is never actually going to be removed?
Thanks a lot!

The TTL shouldn't matter if you deleted the data, since to my understanding
the delete should shadow the data signaling to C* that the data is a
candidate for removal on compaction.
Others might know better, but it could very well be the fact that
gc_grace_seconds is 0 that is causing your problem
I wrote a data migration application which I was testing, and I pushed it too
hard and the FlushWriter thread pool blocked, and I ended up with dropped
mutation messages. I compared the source data against what is in my cluster,
and as expected I have missing records. The strange thing is that m
What consistency level were the writes?
