Description copied from class: ApiRequestHandler

Handles a request. The is populated at this point.

Specified by:

handle in class ApiRequestHandler<QueryRequestReader,QueryResponseWriter>

Parameters:

partitionId - the current partition id

requestId - the current request id

requestReader - a reader that is already populated with the request data

responseWriter - a writer that can be used to write successful responses

errorWriter - a ErrorResponseWriter that can be used to write error responses

Returns:

a ErrorResponseWriter when the handling failed, or a ResponseWriter when the handling was successful. Writes to the other writer will be ignored and are not sent as a response.
