Multiple unrelated nodebb instances in a redis database
Hello, can I run multiple nodebb instances in a single redis database (not server but db) so I want to run unknown x number of nodebbs and I can't preconfigure them to use different dbs like 0 1 2 3 ... what I want is setting all to db 0 of redis and let them run.
This translates down to if nodebb supports tableprefixing? Thus multiple nodebbs can use the same database without touching each other's data. Security is not an issue for me in this context.
No, NodeBB doesn't support it. Why not just use multiple databases?
