From what I see, for most events, `maybeUpdate` is called. I assume that we only want to update a live application if it hasn't been updated in the last configured period. For the `SparkListenerStageExecutorMetrics` event, according to Edwina's comment, this is only processed when reading event logs, so `update` is called in that case. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
