cassandra-stress where query with greater than operator

Hi All. I'm trying to set up cassandra load testing and came up with the next YAML config (https://gist.github.com/folex/d297cc8208a2e54a36d7) : keyspace: stress keyspace_definition: | CREATE KEYSPACE stress WITH replication = {'class': 'SimpleStrategy', 'replication_factor': 3}; table:

Re: Importing data from SQL Server

I had to write my own, but not due to lack of support. I found I needed to preprocess the data before I put it into cassandra, you might find that beneficial. I only had 3 massive tables to worry about so it wasn't that much extra work to code it out - your case might be different if you have 50

Re: Not able to cqlsh on 2.1.9 on Ubuntu 14.04

I assume "@ Of node" is ethX's IP address? Has cassandra been restarted since changes were made to cassandra.yaml? The netstat output that you posted doesn't look right; we use settings similar to what you've posted. Here's what it looks like on one of our nodes. -Jared On 14 September 2015 at

Hi All. Thanks for your replies. a) cqlsh does not work either :( b) Following are the parameters as asked :: listen_address: localhost rpc_address: localhost broadcast_rpc_address is not set. According to the yaml file :: # RPC address to broadcast to drivers and other Cassandra nodes.

Re: Not able to cqlsh on 2.1.9 on Ubuntu 14.04

Is there a reason that you're setting listen_address and rpc_address to localhost? listen_address doc: "the Right Thing is to use the address associated with the hostname". So, set the IP address of this to eth0 for example. I believe if it is set to localhost then you won't be able to form a

By default, stress runs stop after throughput has not improved after three runs. This functionality is a little difficult to figure out from the documentation, so take a look at (maybe even with a debugger attached):

Hi All. I re-established my server from scratch, and installed the 21x server. Now, cqlsh works right out of the box. When I had last setup the server, I had (accidentally) installed the 20x server on first attempt, removed it, and then installed the 21x series server. Seems that caused some

LTCS Strategy Resulting in multiple SSTables

We are using Level Tiered Compaction Strategy on a Column Family. Below are CFSTATS from two nodes in same cluster, one node has 880 SStables in L0 whereas one node just has 1 SSTable in L0. In the node where there are multiple SStables, all of them are small size and created same time stamp.
