+## Partition Statistics
+
+### `compute_partition_stats`
+
+This procedure computes the [partition
stats](../../spec.md#partition-statistics) incrementally from the last snapshot
that has a `PartitionStatisticsFile`
+until the given snapshot (uses current snapshot if not specified) and writes
the combined result into a `PartitionStatisticsFile`.
+It performs a full compute if the previous partition statistics file does not
exist. It also registers the
+`PartitionStatisticsFile` to the table metadata.
+
+| Argument Name | Required? | Type | Description
|
+|---------------|-----------|---------------|--------------------------------------------------------------------------------|
+| `table` | ✔️ | string | Name of the table
|
+| `snapshot_id` | | string | Id of the snapshot to compute
partition stats. Defaults to current snapshot id |
+
+#### Output

created from by command |

+#### Examples
+
+Collect partition statistics of the latest snapshot of table `my_table`
+```sql
+CALL catalog_name.system.compute_partition_stats('my_table');

+Collect partition statistics of the snapshot with id `snap1` of table
`my_table`
