Today, we publish additional query metrics that can help customers understand Amazon Athena performance. Athena publishes query-related metrics to Amazon CloudWatch. With this release, Athena will publish four additional query metrics. They are:
Query Planning Time, the time taken to plan the query. This includes the time spent retrieving table partitions from the data source,
Query Queuing Time, the time that the query was in a queue waiting for resources,
Service Processing Time, the time taken to write results after the query engine finished its execution,
Total Execution Time, time Athena took to run the query.
