I recognize that behind the scenes there's connection pooling and all kinds
of nice asynchronous dispatch of requests to cassandra, but is there any
sort of reason to avoid using different Java clients in the same
application?
I'm noticing that some are better suited to certain kinds activity than
Tried using Cassandra as a queue once. It's an attractive idea, having the
data replicated and durably stored. However the problems we hit were with
trying to utilize a secondary index for whether or not something had been
processed or not. Since that index field was basically on a type with

Looks nice!

What's the version number of Cassandra?

I had this happen when I had really poorly generated tokens for the ring.
Cassandra seems to accept numbers that are too big. You get hot spots
when you think you should be balanced and repair never ends (I think there
is a 48 hour timeout).

I've been trying to understand the overhead of create/drop keyspace on
Cassandra 1.0.8. It's not free, especially when I've managed to drive up
the LiveDiskSpaceUsed for the Migrations CF in the "system" keyspace up to
over 12 MB of disk.
I've tried doing "nodetool -h localhost repair system" and
This is all very hypothetical, but I've been bitten by this before.
Does row_loaded happen to be a binary or boolean value? If so the
secondary index generated by Cassandra will have at most 2 rows, and
they'll be REALLY wide if you have a lot of entries. Since Cassandra
doesn't distribute colum
