> Project: Apache Drill
> Issue Type: New Feature
> Affects Versions: 1.17.0
> Reporter: Arina Ielchiieva
> Assignee: Arina Ielchiieva
> Priority: Major
> Fix For: 1.18.0
>
>
> Currently Drill has only one Metastore implementation based on Iceberg
> tables. Iceberg tables are file based storage that supports concurrent writes
> / reads but required to be placed on distributed file system.
> This Jira aims to implement Drill RDBMS Metastore which will store Drill
> Metastore metadata in the database of the user's choice. Currently,
> PostgreSQL and MySQL databases are supported, others might work as well but
> no testing was done. Also out of box for demonstration / testing purposes
> Drill will setup SQLite file based embedded database but this is only
> applicable for Drill in embedded mode.
