Re: What is substituting keys_cached column family argument

Rob, Have you played with this I have many CFs, some big some small some using large caches some using small ones, some that take many requests, some that take a few. Over time I have cooked up a strategy for how to share the cache love, even thought it may not be the best solution to the

RE: Freeing up disk space on Cassandra 1.1.5 with Size-Tiered compaction.

Having so much data on each node is a potential bad day. Is this discussed somewhere on the Cassandra documentation (limits, practices etc)? We are also trying to load up quite a lot of data and have hit memory issues (bloom filter etc.) in 1.0.10. I would like to read up on big data usage

For background http://wiki.apache.org/cassandra/Operations?highlight=%28snapshot%29#Consistent_backups If you it for a single node then yes there is a chance of inconsistency across CF's. If you have mulitple nodes the snashots you take on the later nodes will help. If you use CL QUOURM for

Re: Freeing up disk space on Cassandra 1.1.5 with Size-Tiered compaction.

Meaning terabyte size databases. Lots of people have TB sized systems. Just add more nodes. 300 to 400 Gb is just a rough guideline. The bigger picture is considering how routine and non routine maintenance tasks are going to be carried out. Cheers - Aaron Morton
