ryan rawson commented on HBASE-2501:
------------------------------------
right now HFile knows very little about its surrounding context. It literally
only knows the very few flags passed to it. There are no package dependencies
on regionserver and that is probably the right direction.
However as we expand our advanced use, we might want to make HFiles slightly
smarter - for example they are for specific tables and regions. If a HFile
knew that info, it could tell the block cache to get better caching stats.
But I would still maintain that keeping more advanced handling such as blooms,
etc out of HFile would be best. Right now its a simple to test sub-module,
lets keep it that way.
> Refactor StoreFile Code
> -----------------------

> Key: HBASE-2501
> URL: https://issues.apache.org/jira/browse/HBASE-2501
> Project: Hadoop HBase
> Issue Type: Improvement
> Components: regionserver
> Affects Versions: 0.20.5
> Reporter: Nicolas Spiegelberg
> Priority: Minor
> Fix For: 0.20.5
>
>
> Currently, the StoreFile code is a thin wrapper around an HFile.Reader. With
> the addition of BloomFilters and other features that operate at the HFile
> layer, we need to clarify the difference between a StoreFile & HFile. To
> that end, we need to refactor the StoreFile.Reader code and the code that
> inter-operates with it.
