Would like to have detailed explanation documentation on presto query statistics like totalCPutime, totalExecutionTime, totalBlockedTime etc.
Can i work on this?
Go for it @Akanksha-kedia
@AbhijitKulkarni1 @tdcmeehan can you give me details regarding this, wat is the expectation, wat details, and any reference?
@Akanksha-kedia Please refer to the QueryStats class and infer from the code the meaning of the statistics.
@Akanksha-kedia If you can highlight the documentation on how these metrics are calculated and explain the metrics would be of great help to understand the Presto query execution for any optimization better.
@Akanksha-kedia it's currently not documented in the code, so the only way is to infer the meaning from the code. In general, it's not difficult to read the intent of this code directly.
