To cache 100% set the value to 1. The comments in the yaml below do explicitly say this, but its discussed here http://wiki.apache.org/cassandra/StorageConfiguration?highlight=(keys)|(cached)

I tried a few variations, but when it set it to: 100% or “100%” or similar I get:

It looks like if it’s yaml it doesn’t pass through the FBUtils.parseDoubleOrPercent(), and since the bean has a double the yaml deserializer is blowing up... Just a guess..

It should do, this is the comment from the yaml
# - keys_cached: specifies the number of keys per sstable whose

Is it not working?

Does 0.7 not support percentages in the keys_cached (in the yaml config)? (I’m on 07.0b2 so maybe it has been fixed?)
thanks
