"Redis Cluster does not support multiple databases like the standalone version of Redis. There is just database 0 and the SELECT command is not allowed."

@leibale ,
I do not understand you, really ?
how you see, that I am talking about multi databases?
if you not understand the question please ask.

I'm using today with "ioredis" library
in ioredis my configuration connection is

{
        sentinels: [{ host: '<ip>', port: <port>},
            { host: '<ip>', port: <port> },
            { host: '<ip>', port: <port> }],
        name: '<name>',
        password: '<password>',
        sentinelRetryStrategy: function (times) {
            return Math.min(times * 10, 1000)
        },
        db: 2
    }

and this is working for me.
but the library make me support new command in code.
they not support it naturally when I just connect to redis.
such as set (members) some of the commads need to sign for them.
make it so harder then to use redis library

now I want to use redis and this configuration is from yours doc

{
        rootNodes: [
            {
                url: `redis://<ip>:<port>`,
            },
            {
                url: `redis://<ip>:<port>`,
            },
            {
                url: `redis://<ip>:<port>`,
            }
        ],
        defaults: {
            username: REDIS_USERNAME,
            password: REDIS_PASSWORD,
            database: 2
        }

    }

and it not working for me.
the error is throw that the bug error title
only database is do, is connecting to database 2 and not for default is 0

now I hope is more clearly
and hope get answer,
and if you do not want to help bring another one to answer
