Anoop Sam John commented on HBASE-15314:
----------------------------------------
So in order to have the clear randomness while filling in files itself, we may
have to have all sized buckets (we have by def 14 buckets of diff sizes) in all
files. The buckets allocation in entire BC's capacity (offset of each bucket
being decided) and allocation for each of the HFile block happens at an upper
layer to IOEngine impl (BucketAllocator).. I feel this will be a much bigger
change. Can we do that as a follow on issue?
In read case we will have randomness mostly.. That depends on which blocks we
will read..
> Allow more than one backing file in bucketcache
