Parth Chandra updated DRILL-2395:
---------------------------------
Fix Version/s: 1.1.0
> Improve interpreted expression evaluation to only call the setup method once
> per batch
> --------------------------------------------------------------------------------------
>
> Key: DRILL-2395
> URL: https://issues.apache.org/jira/browse/DRILL-2395
> Project: Apache Drill
> Issue Type: Improvement
> Components: Functions - Drill
> Reporter: Jason Altekruse
> Assignee: Jason Altekruse
> Priority: Minor
> Fix For: 1.1.0
>
>
> This enhancement request came out of the review for a patch for DRILL-2060.
> Copied below is the discussion from there:
> Jinfeng:
> Do you have a plan to move setup() call into places such that setup() will be
> called once for each VectorAccessible input?
> In the code compile + evaluation model, doSetup() will be called per batch,
> in stead of per row.
> Jason:
> I have started working on a fix for this. Its a little complicated with
> setting constant inputs before the setup method is called. I'm trying to
> figure out the best way to share code with the rest of the input passing used
> in the EvalVisitor. Would you be okay with this being opened as an
> enhancement request to be merged a little later? Considering the current use
> of the interpreter this won't have an impact on any actual queries today.
