# General
* Improve performance of queries with distinct aggregations using table statistics.  ({issue}`15927`)
The choice of whether `MarkDistinct` operator is used for distinct aggregations is now configurable using a new configuration property `optimizer.mark-distinct-strategy` with the values `NONE`, `ALWAYS` and `AUTOMATIC`, with
`AUTOMATIC` as the default.
The `optimizer.use-mark-distinct` configuration property is deprecated in favour of the new property. If used, its values are mapped to the `optimizer.mark-distinct-strategy` property as `true` -> `AUTOMATIC`, `false` -> `NONE`.
