Connect to database non-zero

It seems to me (unless I'm missing something) that lua-resty-redis only allows you to connect to database 0 of redis. You cannot specify another number.

ie this uri connects to database 7

redis://[email protected]:6379/7

@CBarraford Just use the select() method to choose which "database" to use. See the original redis documentation for the corresponding select command for more details:

Thanks. But I was hoping for a way to connect to a specific db. Not connect to db 0 and switch to db 1 everytime I connect.

@CBarraford You can check if the connection comes from the connection pool by means of the get_reused_times method. You only need to run the select command if it is a newly established connection.

BTW, if you have connections to different databases (but to the same redis server), then you also need separate connection pools for different databases (by specifying the "pool" option of the connect method).

Thanks.

I tried red:select(4) but it still saved data in db0.
