To cache 100% set the value to 1. The comments in the yaml below do explicitly say this, but its discussed here|(cached)

I tried a few variations, but when it set it to: 100%  or ď100%Ē or similar I get:

It looks like if itís yaml it doesnít 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
#        locations we keep in memory in "mostly LRU" order.  (JUST the key
#        locations, NOT any column values.) Specify a fraction (value less
#        than 1) or an absolute number of keys to cache.  Defaults to 200000
#        keys.

Is it not working?

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