Hi,
We need help with choosing correct tokens for ByteOrderedPartitioner
Originally the key where supposed to be member_id-mmdd
but since we need to male rage scans on same member_id and varying date
ranges mmdd
we decided to use ByteOrderedPartitioner, so we need that same member
wil
Anyone can help with this?
Thanks

ranges - then
two md5(member_id1) & md5(member_id2) end up very close so
using md5(member_id1)+mmdd & md5(member_id2)+mmdd will cause
range overlaps with ByteOrderedPartitioner.
Thanks

Hi,
I'm interested in using some smart proxy cassandra process that could
act as coordinator node and be aware of cluster state.
And run this smart proxy cassandra process on each client side host
where the application(php) with short lived cassandra connections runs.
Besides being aware of
re of the
ring state and the protocol and if smaprt proxy was the cassandra
itself then it would have all the needed features tested and reliable at
no effort.
Thanks
Alex
Good luck!

I had a schema disagreement problem in cassandra 1.0.9 cluster, where

Hi,
There is a 12 node cluster , still stuck on 1.0.8.
All nodes in the cluster ring are balanced.
Using random partitioner.
All CFs use compression.
Data size on nodes varies from 40G to 75G.
This variance is not due to the bigger nodes having more uncompacted
sstables than others.

Hi,
Below I try to give a full picture to the problem I'm facing.
This is a 12 node cluster, running on ec2 with m2.xlarge instances (17G
ram , 2 cpus).
Cassandra version is 1.0.8
Cluster normally having between 3000 - 1500 reads per second (depends on
time of the day) and 1700 - 800 writes p
ng up with the pace.
tnx
