New Protocol Errors
It is proposed to use existing / add these error codes to the protocol.
Error | Description | Requests |
|---|---|---|
TopicExists | Topic with this name already exists. | CreateTopic |
InvalidTopic (existing) | Topic name contains invalid characters or doesn't exist. | CreateTopic, AlterTopic, DeleteTopic |
InvalidPartitions | Partitions field is invalid (e.g. negative or increasing number of partitions in existing topic) | CreateTopic, AlterTopic |
InvalidReplicationFactor | ReplicationFactor field is invalid (e.g. negative) | CreateTopic, |
InvalidReplicaAssignment | ReplicaAssignment field is invalid (e.g. contains duplicates) |
|
InvalidConfiguration | Either topic-level config setting or value is incorrect. | CreateTopic |
Generally, a client should have enough context to provide descriptive error message.
The same notation as in A Guide To The Kafka Protocol is used here.
