Splitting Bloom filters into multiple meta blocks and loading those blocks on demand to avoid
blocking on large Bloom filter loads at read time
-----------------------------------------------------------------------------------------------------------------------------------------------

                 Key: HBASE-3763
                 URL: https://issues.apache.org/jira/browse/HBASE-3763
             Project: HBase
          Issue Type: Improvement
          Components: regionserver
    Affects Versions: 0.90.2, 0.90.1, 0.90.0, 0.89.20100924
            Reporter: mikhail
            Priority: Minor
             Fix For: 0.89.20100924


Adding 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 behavior is controlled by
the io.storefile.bloom.lazy configuration option, which is set to false by default. Existing
StoreFiles with single-block Bloom filters are handled the same way as before.
