@ofekshenawa @chayim This change will break users using Redis version < 7.2 which doesn't support the CLIENT SETINFO command. The previous version works well since the command error was ignored, bringing them into the pipeline will throw an error.

BTW, I think it'd be better to set DisableIndentity to true by default, for the sake of 7.2 is too new to most users. I will be happy to send a PR to resolve this if it sounds good to you!

Hello! This was released in a minor update release, but it would break all our apps, since we are using KeyDB and as far as I see it does not support CLIENT SETINFO.

Looking at the references to this PR, we are not the only ones having issues.

Are there plans for fixing this or workarounds available?

Same for me, I think there is a regression or a breaking change. I run into this error while calling redis client.Ping: ERR unknown subcommand 'setinfo'. Try CLIENT HELP.
