Connect to Multiple Redis Instance using ServiceStack

Question

I have multiple redis instances on my host (ports 6379, 6380). Currently I'm able to connect to the first instance (6379) using the setup below:

services.AddSingleton<IRedisClientsManager>(p =>
               new PooledRedisClientManager(Configuration.GetValue<long>("Redis:DatabaseId"), Configuration.GetValue<string>("127.0.0.1:6379"))
               {
                   ConnectTimeout = Configuration.GetValue<int>("Redis:connectTimeOut"),
                   IdleTimeOutSecs = Configuration.GetValue<int>("Redis:idleTimeOutSecs"),
                   PoolTimeout = Configuration.GetValue<int>("Redis:poolTimeOut")
               });

Given past experiences with Single Redis instance or Redis sentinel, i have decided to split mutually exclusive operations across multiple Redis instances to spread the work load

for example:

All Operation A will use the 6379 instance while All Operation B will use the 6380 instance

I have read ServiceStack documentation but didn't find any relevant information.

Any suggestion on how this can be achieved?

As you've configured your PooledRedisClientManager with both primary and replica servers, when you resolve a read/write client, i.e:

using var redis = clientsManager.GetClient();

It will resolve the client connected to the primary server, whilst when resolving a readonly client:

using var redisReadOnly = clientsManager.GetReadOnlyClient();

It will resolve a client connected to one of the replicas instead.
