Subject Populating Operator Table
Date Tue, 05 Apr 2016 05:23:29 GMT
Hey y’all,

It seems an instance of DrillOperatorTable is created per query <https://github.com/apache/drill/blob/master/exec/java-exec/src/main/java/org/apache/drill/exec/ops/QueryContext.java#L89>.
With type inference changes, this adds to the query startup time (not part of query time,
rather “run query” request handling time). This object could be initialized once in DrillbitContext,
and used across queries. So is there anything query specific that requires this object to
initialized within QueryContext?

Thank you,
Sudheesh
