Hello. I am tinkering with Metabase in an Elastic Beanstalk environment. I have it connected to an AWS hosted AWS MySQL RDS service. I was adjusting some various values in the Metabase UI like LDAP settings. I assumed the changes would be stored in my RDS instances, but I see NO new database tables created containing this data. Did I miss a step somewhere?
Hi @TomT
Metabase currently does not support MySQL RDS, only Postgres RDS, so your data is stored there - unless you told it not to use RDS, which means it’s stored in H2 on the container and you’ll lose the information if you restart the container.
I would recommend starting over, and connect to Postgres RDS:
https://www.metabase.com/docs/latest/operations-guide/running-metabase-on-elastic-beanstalk.html
You can check Admin > Troubleshooting > Diagnostic Info to see which application database is being used.
Flamber,
Thanks for the reply. My v0.35.3 version of Metabase has a drop option that lists MySQL. This gives me the impression it supports it MySQL. shrugs
@TomT I don’t understand what you mean, where? The latest release is 0.36.4
Metabase support MySQL as it’s application database, just not on EBS:

Again, thanks for the help. Perhaps, I misunderstood you. You said, “MB doesn’t support MySQL RDS”. My version, 0.35.3 has a drop down database type that includes MySQL. This gives me the impression that MySQL is a supported database option. Unless you’re trying to say MySQL (self installed = supported) vs MySQL RDS (not supported).
Thanks,
Tom
@TomT Please post “Diagnostic Info” from Admin > Troubleshooting.
There’s two types of databases in Metabase - the internal application database, where all Metabase information is stored - and your external databases (data sources) setup in Admin > Databases.

@TomT Okay, so you didn’t follow the guide or skipped steps, since you’re using H2:
"application-database": "h2",
But it also looks like this is not a clean EBS setup, otherwise it would say:
"hosting-env": "elastic-beanstalk" instead of "hosting-env": "unknown",
You need to access the instance and get the H2 database out, then setup a Postgres RDS, migrate the data there and then you can setup a new EBS using the existing Postgres RDS.
Make sure you have plenty of backups before doing anything, so you don’t lose all your Metabase data.
