Hi,
What's the correct procedure to drop a keyspace? When I drop a keyspace, the
files of that keyspace don't get deleted. There is a JIRA on this:
https://issues.apache.org/jira/browse/CASSANDRA-4075
Is this a bug or I'm missing something?
I'm using Cassandra 1.1.2 on Ubuntu Linux with Sun JV
Hi
As a part of the Cassandra upgrade to 1.1.2 from 1.0.6, I am running
*nodetool drain* node by node to empty the commit logs. When draining a
particular node, that node accepting READ+WRITE request from the clients and

Yikes. You should read:

Essentially what it sounds like your are now running into is this:
The BloomFilters for each SSTable must exist in main memory. Repair
tends to create some extra data which normally gets compacted away
later.

I'm trying to determine if there are any practical limits on the amount of data
that a single node can handle efficiently, and if so, whether I've hit that
limit or not.
We've just set up a new 7-node cluster with Cassandra 1.1.2 running under
OpenJDK6. Each node is 12-core Xeon with 24GB of RA

*nodetool* operation before shutting down one node in 3 node development

The only possible issue there is with connections and connection pooling,
where you need to set a working keyspac

Yep, it's still there (see validateFilterClauses from line 531):

There should be at least one "=" (equals) in the WHERE case on key or
secondary index column, this is the Cassandra limitation.
