> During my work on a new compaction policies (HBASE-14468, HBASE-14477) I had
> to modify the existing code of a StoreFile.Writer to add additional meta-info
> required by these new policies. I think that it should be done by means of a
> new Plugin framework, because this seems to be a general capability/feature.
> As a future enhancement this can become a part of a more general
> StoreFileWriter/Reader plugin architecture. But I need only Meta section of a
> store file.
> This could be used, for example, to collect rowkeys distribution information
> during hfile creation. This info can be used later to find the optimal region
> split key or to create optimal set of sub-regions for M/R jobs or other jobs
> which can operate on a sub-region level.
