---------------------------------
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"));
}
