Jeff Hammerbacher commented on CASSANDRA-222:
---------------------------------------------
I missed the discussion where it was decided that touch was a bad idea. I don't have an opinion either way, just curious to hear why it is being removed.

Jonathan Ellis commented on CASSANDRA-222:
------------------------------------------
1. the part that is supposed to cache the index positions in a LRU doesn't work
2. the part that does a data read so it will be in the OS disk cache (a) doesn't work for large rows and (b) isn't as accurate as doing an actual get call would be
3. (2) isn't worth addressing because doing touch + get will never be faster than just doing a get in a FutureTask or the equivalent. (1) might be worth fixing but I'll leave that to someone who actually needs the feature.
