+Datasets that are partitioned by a less-granular time-column (e.g. day, month, year) can also use the `time_partition_column` parameter in addition to the `time_column` parameter to specify the time-column to use for efficient partition pruning.

 ### Changes (CDC)
 
 Datasets configured with acceleration `refresh_mode: changes` requires a [Change Data Capture (CDC)](/docs/features/cdc/index.md) supported data connector. Initial CDC support in Spice is supported by the [Debezium data connector](/docs/components/data-connectors/debezium.md).

+## `time_partition_column`
+
+(Optional) Specify the column that represents the physical partitioning of the dataset when using append-based acceleration. When the defined `time_column` is a fine-grained timestamp and the dataset is physically partitioned by a coarser granularity (for example, by date), setting `time_partition_column` to the partition column (e.g. date_col) improves partition pruning, excludes irrelevant partitions during refreshes, and optimizes scan efficiency.
+
+## `time_partition_format`
+
+(Optional) Define the format of the `time_partition_column`. For instance, if the physical partitions follow a date format (YYYY-MM-DD), set this value to `date`. The same format options as `time_format` are supported for `time_partition_column`.
+
 ## `unsupported_type_action`
 
 Optional. Specifies the action to take when a data type that is not supported by the data connector is encountered.
