Nishant Bangarwa updated HIVE-20468:
------------------------------------
Component/s: Druid integration
> Add ability to skip creating druid bitmap indexes for specific string dimensions
> --------------------------------------------------------------------------------
>
> Key: HIVE-20468
> URL: https://issues.apache.org/jira/browse/HIVE-20468
> Project: Hive
> Issue Type: New Feature
> Components: Druid integration
> Reporter: Nishant Bangarwa
> Assignee: Nishant Bangarwa
> Priority: Major
>
> Currently we create bitmap index for all druid dimensions.
> For some columns (e.g Free form text, high cardinality columns that are rarely filtered
upon), It may be beneficial to skip creating druid bitmap index and save disk space.
> In druid https://github.com/apache/incubator-druid/pull/5402 added support for creating
string dimension columns without bitmap indexes.
> This task is to add similar option when indexing data from hive.
