> when an APISIX node crashes and is unable to perform the "decrement count" operation, this key remains permanently in Redis as there is not expiry configured, causing the user's concurrency quota to be permanently occupied or even the user to be banned. Setting a TTL for Redis keys does not seem to solve the scenario where a node in an APISIX cluster goes down under high traffic. When the traffic is heavy, APISIX keeps performing Redis operations, which continuously refresh the TTL. As a result, the counter associated with the failed node in Redis cannot be reset through TTL expiration. -- This is an automated message from the Apache Git Service.
