What causes "not implemented" in go-redis/redis?

Do not call Quit; close the client with client.Close() instead.

not implemented

Error message

not implemented

What it means

The Quit method panics with 'not implemented'. Quit is deprecated as of Redis 7.2.0; the comment says to just close the connection. The method signature is retained on the Cmdable interface but its body deliberately panics because QUIT must close the calling connection, which the pooled client model does not support.

Solutions

Do not call Quit; close the client with client.Close() instead.
Remove any Quit references and rely on connection-pool teardown.
If you need a per-connection close, use a raw Conn via client.Conn().

Example fix

// before
client.Quit(ctx)

// after
client.Close()

Defensive patterns

Strategy: validation

Validate before calling

// Quit is intentionally unsupported. Validate at the call site by not calling it.
// Replace any client.Quit(ctx) with client.Close().

Prevention

Search the codebase for '.Quit(' and remove/replace every occurrence.
Do not generate command calls from the Redis command catalogue without filtering deprecated/unsupported stubs.
Use client.Close() for teardown.

When it happens

Trigger: Calling client.Quit(ctx) (or invoking it through the Cmdable interface) on any client type.

Common situations: Porting code from another Redis client that issues QUIT, or auto-generating command calls from a Redis command list without checking deprecation.
