For the case of reading a file, I wonder if it only drops the caches on the
replicas it read from of from all replicas (even then ones it did not read from.
One case where dropping the caches could have an impact is when a file is
shared between multiple tablets. A situation like the following.
* Table A has files F1,F2,F3
* Table A splits into Tablets B and C
* Tablet B compacts F1 and F2 into F4
* Tablet C is running scans against F1 and F2
In the case above maybe the compaction for Tablet B could cause some
performance problems for Tablet C. I don't think this case is something to
worry about, I just thought it was interesting.
