I've dug deeper into this, since this got my script running but still left
me at sea when dealing with the actual data. It's looking like there may be
a mismatch between the schema that's being reported by
CassandraStorage.java, and the data that's actually returned. Here's an
example:

Thanks for that hint! However, it seems like soundex is a very language
specific algorithm (US English). We have to get into this topic further...
Kind regards

What measure are you using to say Cassandra does not shut down ?
Can you get a thread dump to see what's still running ?

Sort order is determined by the Comparator, which is an implementation of the
o.a.c.db.marshal.AbstractTypeT class.
If you wish to order column (names) in a row based on an opaque (to cassandra)
byte value you can create your own implementation. You would then need to
decrypt and compare
It depends on what your workload is and how you want to read the data.
If you want to get all the data for an article every time, and the number of

Even after disabling hinted handoff and setting read_repair_chance to 0 on all
our column families, we were still experiencing massive writes. Apparently the
read_repair_chance is completely ignored at any CL higher than CL.ONE. So we
were doing CL.QUORUM on reads and writes and seeing
I've already posted to the elasticsearch groups and thought it prudent to
also ask here.
We are looking at using elastic search to index our data that we currently
store to Cassandra. I was wondering if there are any concerns running

Hi there,
If you start cassandra-cli with --debug it will output a stack trace if
the error is client side.

Look in jconcole - org.apache.cassandra.db - ColumnFamilies
bloom filter false ratio is on this server 0.0018 and 0,06% reads hits
more than 1 sstable.
From cassandra point of view, it looks good.
