Hi
We have a 6 node cluster in two DCs, Cassandra version 1.1.11, RF=3 in each DC.
The DataStax Documentation says the following:
Initiate a major compaction through nodetool compacthttp://www.datastax.co=
This question is specific to Thrift - but in the process of moving to CQL - so
either client will be fine.
Thanks
How do you determine the slow node, client side response latency?

Hi
I have 2 data centers - with 3 nodes in each DC - version 1.1.6 - replication
factor 2 - topology properties:

Slight correction - replication factor is 3.
Will obtain nodetool ring info to verify tokens.

Did you alternate your tokens? I may be off base - but if not then that's why
you might be seeing cross-dc request.

I don't think that issue applies if the node has been down long enough to be
marked as down though.

The datastax documentation concisely describes how to configure and
assure that the properties are used in client access. Question is this:
if using the thrift api login, does C* use the Authentication class to
determine access privileges based on the access/passwd properties?

Further info - it seems I had the seeds list backwards - it did not need
both nodes - I have corrected that with each pointing to the other as a
single seed entry - and it works fine.
Thanks again for the quick response.

This question relates to a C++ client application, to direct the
Cassandra request to the correct Cassandra node based on token form of
the key.
Would the following work? If the token form of the key could be
determined - the keyspace description could be used to select the
