Description copied from class: AbstractSqlGatewayRestHandler

This method is called for every incoming request and returns a CompletableFuture containing a the response.

Implementations may decide whether to throw RestHandlerExceptions or fail the returned CompletableFuture with a RestHandlerException.

Failing the future with another exception type or throwing unchecked exceptions is regarded as an implementation error as it does not allow us to provide a meaningful HTTP status code. In this case a HttpResponseStatus.INTERNAL_SERVER_ERROR will be returned.

Specified by:

handleRequest in class AbstractSqlGatewayRestHandler<ResumeEmbeddedSchedulerWorkflowRequestBody,org.apache.flink.runtime.rest.messages.EmptyResponseBody,org.apache.flink.runtime.rest.messages.EmptyMessageParameters>

Parameters:

version - request version

request - request that should be handled

Returns:

future containing a handler response

Throws:

org.apache.flink.runtime.rest.handler.RestHandlerException - if the handling failed
