handleResponse

public AdminApiHandler.ApiResult<CoordinatorKey,TransactionDescription> handleResponse(org.apache.kafka.common.Node broker,
 Set<CoordinatorKey> keys,
 org.apache.kafka.common.requests.AbstractResponse abstractResponse)

Description copied from interface: AdminApiHandler

Callback that is invoked when a request returns successfully. The handler should parse the response, check for errors, and return a result which indicates which keys (if any) have either been completed or failed with an unrecoverable error. It is also possible that the response indicates an incorrect target brokerId (e.g. in the case of a NotLeader error when the request is bound for a partition leader). In this case the key will be "unmapped" from the target brokerId and lookup will be retried. Note that keys which received a retriable error should be left out of the result. They will be retried automatically.

Parameters:

broker - the broker that the associated request was sent to

keys - the set of keys from the associated request

abstractResponse - the response received from the broker

Returns:

result indicating key completion, failure, and unmapping
