Metastore
URL: https://github.com/apache/drill/pull/2060#issuecomment-615395578
@arina-ielchiieva, another related question. We currently use ZK to store
things like plugin configs, dynamic UDFS, etc. Charles just asked about the
problems storing credentials that way.
I wonder if the DB support here is (or can be) generalized to allow a
variety of stores (the way we have multiple "pstores" for ZK.) If so, then,
over time, we could implement alternative, DB-based "pstores" for plugins,
UDFs, security credentials and more.

> Key: DRILL-7706
> URL: https://issues.apache.org/jira/browse/DRILL-7706
> 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.
