[Bug]: rocksdb in app.toml doesn't work

[robert-zaremba]

Is there an existing issue for this?

• I have searched the existing issues

What happened?

Similar to #23133

When setting in app.toml:

app-db-backend = 'rocksdb'

we immediately get the following error:

failed to create SCRawDB: unsupported db type: rocksdb

NOTE: setting rocksdb in config.toml works without any problems.

Cosmos SDK Version

main(v2)

How to reproduce?

• Build: COSMOS_BUILD_OPTIONS=rocksdb,v2 make build
• simdv2 version --long reports build_tags: netgo ledger rocksdb grocksdb_clean_link
• start a basic simapp similarly to [Bug]: pebbledb in app.toml doesn't work #23133 but use rocksdb backend

Based on the error message ([...] SCRawDB [...]), didn't some store/v2 or IAVL/v2 code got into store/v1? My understanding is that store/v1 doesn't follow the SC/SS design.

hey in #23157 we opted to only support pebble db and goleveldb. Goleveldb because it is widely used today and pebble because it is the best out of the box solution for go. other tools like memiavl and iavlv2 will not sure the underlying db here these are only for iavlv1.
