hongbin ma created KYLIN-1591: --------------------------------- Summary: enabling different block size setting for small column families Key: KYLIN-1591 URL: https://issues.apache.org/jira/browse/KYLIN-1591 Project: Kylin Issue Type: Improvement Reporter: hongbin ma Assignee: hongbin ma
the current setting for hbase block size (kylin.hbase.default.block.size) is by default set to a quite large value because cubes can be quite big value(4M) because cubes with memory hungry measures like hll can be quite large. However if a column family does not contain memory hungry measures it does not make sense to be that large. the revised setting will be: public int getHbaseDefaultBlockSize() { return Integer.valueOf(getOptional("kylin.hbase.default.block.size", "1048576")); } public int getHbaseSmallFamilyBlockSize() { return Integer.valueOf(getOptional("kylin.hbase.small.family.block.size", "65536")); } -- This message was sent by Atlassian JIRA (v6.3.4#6332)
