Looks okay to me but, i really don't think using the database to store tenant data is an overkill. Reading a file on disk is slower than reading from a database. Also consider a scenario where you have 100's of tenants and you need to edit a config file to make a single change. You can also consider storing tenant data on a separate database for isolation and scaling.

did you say reading from a file is SLOWER than a database? that is simply not true (and not what i have heard all these years)..

The question should be about making sure data stays the same ie ACID.. which might be difficult to achieve if reading/writing to a file..

of course try searching for something in an array that's really really long vs searching the something on a RDBMS. databases are made for these tasks. If you load an array in to memory and search it you will definitely run out of memory, try doing that per server request.
