I have a cache which consists of multiple standalone Redis instances all behind an Envoy Proxy. As per the Envoy documentation, it is capable of fanning out a multi slot command like MGET to the right Redis instances based on its hash slot. It works as expected when I run such commands through redis-cli.
But in my .NET application, when I issue such command through StackExchange.Redis, it throws an exception saying Multi-key operations must involve a single slot; Wondering is there any way to execute such operations in my step?
StackExchange.Redis.RedisCommandException HResult=0x80131500 Message=Multi-key operations must involve a single slot; keys can use 'hash tags' to help this, i.e. '{/users/12345}/account' and '{/users/12345}/contacts' will always be in the same slot Source=StackExchange.Redis StackTrace: at StackExchange.Redis.ServerSelectionStrategy.Select(Message message, Boolean allowDisconnected) in /_/src/StackExchange.Redis/ServerSelectionStrategy.cs:line 148 at StackExchange.Redis.ConnectionMultiplexer.SelectServer(Message message) in /_/src/StackExchange.Redis/ConnectionMultiplexer.cs:line 1828 at StackExchange.Redis.ConnectionMultiplexer.PrepareToPushMessageToBridge[T](Message message, ResultProcessor1 processor, IResultBox1 resultBox, ServerEndPoint& server) in /_/src/StackExchange.Redis/ConnectionMultiplexer.cs:line 1843 at StackExchange.Redis.ConnectionMultiplexer.TryPushMessageToBridgeSync[T](Message message, ResultProcessor1 processor, IResultBox1 resultBox, ServerEndPoint& server) in /_/src/StackExchange.Redis/ConnectionMultiplexer.cs:line 1905 at StackExchange.Redis.ConnectionMultiplexer.ExecuteSyncImpl[T](Message message, ResultProcessor1 processor, ServerEndPoint server, T defaultValue) in /_/src/StackExchange.Redis/ConnectionMultiplexer.cs:line 1966
