That's the issue - I do not use consistency ALL. I set QUORUM or ONE but it

As far as I understand, it can be caused by read repair attempts (we see

But I still see in log

Hi,
I set default_time_to_live for existing table. Does it affect existing data?
It seems data to be deleted, but after compaction, I don't see any disk space
freed as expected. Database has data for almost year, GC time is ten days, and
TTL is also ten days on one table and 100 days on other.
Hi,
I run repair, then I see that anticompaction started on all nodes.Does it mean
that all data is already repaired. Actually I increased RF, so can I already
use database?
Thanks.

Hi All,
I have Cassandra with Spark on node 10.0.0.1
On other server I run
./spark-shell --master spark://10.0.0.1:7077and then set
val conf = new SparkConf(true).set("spark.cassandra.connection.host",

It works, but I see in tcpdump that Spark node connects to Cassandra with

Hi,
assuming I have new, empty Cassandra cluster, how should I start using

migration procedure anyway? And what happens to new column families?
