When users click the vertex timeline, display all the subtask attempts timeline with subtaskId-host-attemptId.
REST API Design
...
- ArchivedExecutionVertex adds method to return prior executions.
- get prior execution attempt
AccessExecution execution = executionVertex.getCurrentExecutionAttempt();
- by ArchivedExecutionVertex.getPriorExecutionAttempts()
...
JobID jobID = request.getPathParameter(JobIDPathParameter.class);
JobVertexID jobVertexID = request.getPathParameter(JobVertexIdPathParameter.class);
List<SubtaskExecutionAttemptDetailsInfo> allAttempts = new ArrayList<>();
- add
...
if (currentAttemptNum > 0) {
for (int i = currentAttemptNum - 1; i >= 0; i--) {
AccessExecution currentExecution = executionVertex.getPriorExecutionAttempt(i);
if (currentExecution != null) {
allAttempts.add(SubtaskExecutionAttemptDetailsInfo.create(currentExecution, metricFetcher, jobID, jobVertexID));
}
}
}
- add SubtaskAllExecutionAttemptsDetailsHandler for failed attempt
- url /jobs/:jobid/vertices/:vertexid/subtasks/:subtaskIndex/attempts
- response:
{ "id" : "urn:jsonschema:org:apache:flink:runtime:rest:messages:job:SubtaskAllExecutionAttemptsDetailsInfo", "properties" : { "attempts" : { "type" : "array", "items" : { "type" : "object", "id" : "urn:jsonschema:org:apache:flink:runtime:rest:messages:job:SubtaskExecutionAttemptDetailsInfo", "properties" : { "subtask" : { "type" : "integer" }, "status" : { "type" : "string", "enum" : [ "CREATED", "SCHEDULED", "DEPLOYING", "RUNNING", "FINISHED", "CANCELING", "CANCELED", "FAILED", "RECONCILING" ] }, "attempt" : { "type" : "integer" }, "host" : { "type" : "string" }, "start-time" : { "type" : "integer" }, "end-time" : { "type" : "integer" }, "duration" : { "type" : "integer" }, "metrics" : { "type" : "object", "id" : "urn:jsonschema:org:apache:flink:runtime:rest:messages:job:metrics:IOMetricsInfo", "properties" : { "read-bytes" : { "type" : "integer" }, "read-bytes-complete" : { "type" : "boolean" }, "write-bytes" : { "type" : "integer" }, "write-bytes-complete" : { "type" : "boolean" }, "read-records" : { "type" : "integer" }, "read-records-complete" : { "type" : "boolean" }, "write-records" : { "type" : "integer" }, "write-records-complete" : { "type" : "boolean" } } } } } } } |
- add Collection<SubtaskTimeInfo> in SubtasksTimesHandler result, which comes from ExecutionVertex’s prior executions.

- In the 'subtasks' array we have objects of type SubtaskTimeInfo with only one added field 'attempt'.
- add query parameter show-history, default value is false. If show-history is true, information for all attempts including
previous ones will be returned - url: /jobs/:jobid/vertices/:vertexid/subtasktimes?show-history=true
- response:
