erankor opened a new issue #6661: Slow timeBoundary queries
URL: https://github.com/apache/incubator-druid/issues/6661
 
 
   Hi all,
   
   I'm occasionally seeing timeBoundary queries (issued by Swiv) that run for a very long time.
   For example, this query was running for 30 sec - 
   ```
   {
   	"queryType": "timeBoundary",
   	"dataSource": {
   		"type": "table",
   		"name": "reach-usage"
   	},
   	"intervals": {
   		"type": "intervals",
   		"intervals": ["0000-01-01T00:00:00.000Z/3000-01-01T00:00:00.000Z"]
   	},
   	"bound": "maxTime",
   	"filter": null,
   	"context": {
   		"queryId": "515cd6b7-f7a4-46ee-84b3-7c63a78ceaf8",
   		"timeout": 40000
   	},
   	"descending": false
   }
   ```
   What can be the cause of this? can it be related to the MySQL? is Druid performing any SQL queries to answer this?
   (I'm using version 0.10.0)
   
   Thank you,
   
   Eran
