Why Cassandra 2.1.2 couldn't populate row cache in between

Hi,

If I've enable row cache for some column family, when I request some
row which is not from the begining of the partition, then cassandra
doesn't populate, row cache.

Why it is so? For older version I think it was because we're saying
the its caching complete merged partition so, incomplete partition
can't reside in row cache.

However in new version since we could resize the cache, so why not we
populate from other than the start?
