hat's a red herring. More likely data in that row was created with a higher-res timestamp than the delete was issued at. On Thu, May 27, 2010 at 7:27 AM, Bill de hOra wrote: Saw some behaviour today on Cassandra 0.6.1 - After running a remove command on a row in a CF whose CompareWith was Bytes

Remove and BytesType

Saw some behaviour today on Cassandra 0.6.1 - After running a remove command on a row in a CF whose CompareWith was BytesType the row was still there, and still there after bouncing the server. This was the case for hector/cli. When I changed the CompareWith to UTF8Type, new rows added could b

Re: replication impact on write throughput

the client. I'd agree for any individual client; what I'm after is the overall capacity a cluster has over time in the face of replicas. But let's assume it's ConsistencyLevel.ONE - how would you think the available write capacity degrades? Bill On Tue, May 11, 2010

replication impact on write throughput

If I had 10 Cassandra nodes each with a write capacity of 5K per second and a replication factor of 2, would that mean the expected write capacity of the system would be ~25K writes per second because the nodes are also serving other nodes and not just clients? I know this is highly simplified
