; }; Only features from the [Apache 2 Edition](https://docs.tigerdata.com/about/latest/timescaledb-editions/) of TimescaleDB are supported. ## Dashboard Configuration This extension requires activation via the PlanetScale Dashboard before it can be used. It must be enabled through shared libraries and requires a database restart. To enable TimescaleDB: From the PlanetScale organization dashboard, select the desired database Navigate to the **Clusters** page from the menu on the left Choose the branch whose extensions you'd like to configure in the "**Branch**" dropdown Select the **Extensions** tab Enable timescaledb and configure its parameters Click **Queue extension changes** to apply the configuration Once you're ready to apply the changes, click "**Apply changes**" ## Usage After enabling the extension through the dashboard, you'll be able to install it in your Postgres cluster: ```sql theme={null} CREATE EXTENSION IF NOT EXISTS timescaledb; ``` ## External Documentation For more detailed information about TimescaleDB usage, see the [official documentation](https://github.com/timescale/timescaledb). ## Parameters ### timescaledb.enable\_chunk\_append * **Type**: Boolean * **Default**: `true` * **Description**: Enable chunk append node ### timescaledb.enable\_chunk\_skipping * **Type**: Boolean * **Default**: `false` * **Description**: Enable chunk skipping functionality ### timescaledb.enable\_constraint\_aware\_append * **Type**: Boolean * **Default**: `true` * **Description**: Enable constraint-aware append scans ### timescaledb.enable\_constraint\_exclusion * **Type**: Boolean * **Default**: `true` * **Description**: Enable constraint exclusion ### timescaledb.enable\_custom\_hashagg * **Type**: Boolean * **Default**: `false` * **Description**: Enable custom hash aggregation ### timescaledb.enable\_deprecation\_warnings * **Type**: Boolean * **Default**: `true` * **Description**: Enable warnings when using deprecated functionality ### timescaledb.enable\_event\_triggers * **Type**: Boolean * **Default**: `false` * **Description**: Enable event triggers for chunks creation ### timescaledb.enable\_foreign\_key\_propagation * **Type**: Boolean * **Default**: `true` * **Description**: Enable foreign key propagation ### timescaledb.enable\_job\_execution\_logging * **Type**: Boolean * **Default**: `false` * **Description**: Enable job execution logging ### timescaledb.enable\_now\_constify * **Type**: Boolean * **Default**: `true` * **Description**: Enable now() constify ### timescaledb.enable\_optimizations * **Type**: Boolean * **Default**: `true` * **Description**: Enable TimescaleDB query optimizations ### timescaledb.enable\_ordered\_append * **Type**: Boolean * **Default**: `true` * **Description**: Enable ordered append scans ### timescaledb.enable\_parallel\_chunk\_append * **Type**: Boolean * **Default**: `true` * **Description**: Enable parallel chunk append node ### timescaledb.enable\_qual\_propagation * **Type**: Boolean * **Default**: `true` * **Description**: Enable qualifier propagation ### timescaledb.enable\_runtime\_exclusion * **Type**: Boolean * **Default**: `true` * **Description**: Enable runtime chunk exclusion ### timescaledb.enable\_tiered\_reads * **Type**: Boolean * **Default**: `true` * **Description**: Enable tiered data reads ### timescaledb.enable\_tss\_callbacks * **Type**: Boolean * **Default**: `true` * **Description**: Enable ts\_stat\_statements callbacks ### timescaledb.max\_cached\_chunks\_per\_hypertable * **Type**: Integer * **Default**: `1024` * **Min**: `0` * **Max**: `65536` * **Description**: Maximum cached chunks ### timescaledb.max\_open\_chunks\_per\_insert * **Type**: Integer * **Default**: `1024` * **Min**: `0` * **Max**: `32767` * **Description**: Maximum open chunks per insert ### timescaledb.restoring * **Type**: Boolean * **Default**: `false` * **Description**: Enable restoring mode for TimescaleDB
