Ted Yu updated HBASE-11131:
---------------------------
Component/s: Filters
> Improve essential column family handling when more than one
> SingleColumnValueFilter is involved
> -----------------------------------------------------------------------------------------------
>
> Key: HBASE-11131
> URL: https://issues.apache.org/jira/browse/HBASE-11131
> Project: HBase
> Issue Type: Task
> Components: Filters
> Reporter: Ted Yu
> Priority: Minor
>
> Currently, SingleColumnValueFilter determines essential column family based
> on:
> {code}
> public boolean isFamilyEssential(byte[] name) {
> return !this.filterIfMissing || Bytes.equals(name, this.columnFamily);
> {code}
> When more than one SingleColumnValueFilter is used through FilterList, some
> optimization can be done.
> e.g. when they are chained by Operator.MUST_PASS_ALL, the second and
> subsequent SingleColumnValueFilter can declare to be non-essential.
> This way their evaluation would depend on the outcome of the first
> SingleColumnValueFilter.
