I'm guessing your talking about multi-homing because you want to have
multiple tenants (different apps/ teams etc) to make better use of
resources ?
As Jared mentioned running multiple Cassandra processes on the same
hardware that participate in the same cluster doesn't make much sense from

Is != supported as part of the where clause in Cassandra?
It's not.
Or is it the grammar for some other purpose?
It's supported in 'IF' conditions. You can do something like:
SELECT * FROM foo WHERE k = 0 IF v != 3;

Hi all,
i'm unsure if cassandra is appropriate for my use case:
Maintain a query model.
Collect data from several sources (asynchronously) and merge it into
aggregates (rows) in one cassandra table.
The data is mostly updated, except from initial load or adding new data
ranges.
Some source
Only recently! Moving off list (c* users bcc'd).

I think Sylvain may not have had his coffee yet. You can't use IF's in
SELECT statements, but you can in INSERT/UPDATE/DELETE:
UPDATE foo SET a = 0 WHERE k = 0 IF b != 0;

Also be aware of https://issues.apache.org/jira/browse/CASSANDRA-7734 if you
are using C* 2.0.6+ (2.0.6 introduced a change that can sometimes causes
initial schema propagation not to happen, introducing potentially long delays
until some other code path repairs it later)

Hello Matthias
According to your description, an event-sourcing design would be a good
fit for your scenario.
In Cassandra, instead of updating existing data, why don't you just
store new values (it can be delta only, not a problem) with a monotonic
increasing date ?
This way, in your
