 Additionally, the amount of overlap between incremental queries can be configured using the `incrementalQueryOverlapWindow` jsonData field, the default value is `10m` (10 minutes).
 
 Increasing the duration of the `incrementalQueryOverlapWindow` will increase the size of every incremental query, but might be helpful for instances that have inconsistent results for recent data.

+The Prometheus data source can be configured to disable recording rules under the data source configuration or provisioning file (under `disableRecordingRules` in jsonData).
