Hi, I'm using Cassandra 1.0.7 and I've set the keys_cached to about 80% (using the numerical values). This is visible in cfstats too. But I'm getting less than 20% (or sometimes even 0%) key cache hit rate. Well, the data access pattern is not the issue here as I know they are retrieving the same row multiple times. I'm using hector client with dynamic load balancing policy with consistency ONE for both reads and writes. Any ideas on how to find the issue and fix this?
Here is what I see on cfstats. Key cache capacity: 16637958 Key cache size: 16637958 Key cache hit rate: 0.045454545454545456 Also, is there a way to warm start the key cache, meaning pre-load the amount of keys I set as keys_cached? Thanks, Eran
