> Improve schema discovery For Druid Storage Handler
> --------------------------------------------------
>
> Key: HIVE-18780
> URL: https://issues.apache.org/jira/browse/HIVE-18780
> Project: Hive
> Issue Type: Improvement
> Components: Druid integration
> Reporter: slim bouguerra
> Assignee: slim bouguerra
> Priority: Major
> Fix For: 3.0.0
>
> Attachments: HIVE-18780.patch, HIVE-18780.patch
>
>
> Currently, Druid Storage adapter issues a Segment metadata Query every time
> the query is of type Select or Scan. Not only that but then every input split
> (map) will do the same as well since it is using the same Serde, this is very
> expensive and put a lot of pressure on the Druid Cluster. The way to fix this
> is to add the schema out of the calcite plan instead of serializing the query
> itself as part of the Hive query context.
