hbase.io.index.interval need be configuratable in column family
----------------------------------------------------------------
Key: HBASE-700
URL: https://issues.apache.org/jira/browse/HBASE-700
Project: Hadoop HBase
Issue Type: Improvement
Components: regionserver
Affects Versions: 0.1.2
Reporter: LN
Priority: Minor
setting parameter hbase.io.index.interval to smaller can improve hbase reading
performance significantly, esp. in large value size column families. however,
small hbase.io.index.interval cause more memory usage, because all index will
read into memory when loading a mapfile.
in my test env, i set hbase.io.index.interval to 1, after inserting about 3M
samll size records to a table(about 1.5G in hadoop file), the regionserver
throws OOME. then i found total size of map file index is 350M. however, i
can't adjust hbase.io.index.interval to a larger one, like 32, because other
big cell size tables need it be 1.
so, i think make hbase.io.index.interval a column family property should be
very important for performance tuning.
