Zhihong Yu updated HBASE-5032:
------------------------------
Description:
Previously, the delete family bloom filter only contains the row key which has
the delete family. It helps us to avoid the top-row seek operation.
This jira attempts to add the delete column into this delete bloom filter as
well (rename the delete family bloom filter as delete bloom filter).
The motivation is to save seek ops for scan time-range queries if we know there
is no delete column for this row/column.
We can seek directly to the exact timestamp we are interested in, instead of
seeking to the latest timestamp and keeping skipping to find out whether there
is any delete column before the interested timestamp.
