Joydeep Sen Sarma commented on HBASE-3763:
------------------------------------------
Dhruba pointed me to some of these jiras.
one quick comment is that _if_ the intention is to keep the filters pinned in
memory - then we can convert the load at read time to:
- load at startup time as quickly as possible
- keep the filter pinned in memory when writing out new hfile (never have to
read it in)
this would also take out filter reads from client read path.

> Add a way to save HBase Bloom filters into an array of Meta blocks instead of
> one big Meta block, and load only the blocks required to answer a query.
> This will allow us faster bloom load times for large StoreFiles & pave the
> path for adding Bloom Filter support to HFileOutputFormat bulk load.
