------------------------------------------------
bq.If your bucketcache usedsize is only 20GB you get the performance of a
single physical disk with the proposed patch. If you use all files in parallel
you get the performance of all 4 disks.
I am trying learn more here. So here the point is as and when the cache is
filling up only then the usedSize will be growing and reaching upto 100GB
(which is the total size of bucketCache).
The point and need here is that as when you are filling up try to parallelize
the files instead of filling it up one by one. So that initial 20G itself
should be distributed among the four files. Is that so?
> Allow more than one backing file in bucketcache
