@ -35,7 +35,7 @@ At the database level, partitioning involves the use of two dedicated columns to
* **PARTITION_ID** &ndash; This is an integer indicating the specific partition that a given resource is placed in. This column can also be *NULL*, meaning that the given resource is in the **Default Partition**.
* **PARTITION_DATE** &ndash; This is a date/time column that can be assigned an arbitrary value depending on your use case. Typically, this would be used for use cases where data should be automatically dropped after a certain time period using native database partition drops.
When partitioning is used, these two columns will be populated with the same value on all resource-specific tables (this includes [HFJ_RESOURCE](./schema.html#HFJ_RESOURCE) and all tables that have a foreign key relationship to it including [HFJ_RES_VER](./schema.html#HFJ_RES_VER), [HFJ_RESLINK](./schema.html#HFJ_RES_LINK), [HFJ_SPIDX_*](./schema.html#search-indexes), etc.)
When partitioning is used, these two columns will be populated with the same value for a given resource on all resource-specific tables (this includes [HFJ_RESOURCE](./schema.html#HFJ_RESOURCE) and all tables that have a foreign key relationship to it including [HFJ_RES_VER](./schema.html#HFJ_RES_VER), [HFJ_RESLINK](./schema.html#HFJ_RES_LINK), [HFJ_SPIDX_*](./schema.html#search-indexes), etc.)
At the time that a resource is being **created**, an [interceptor hook](#partition-interceptors) is invoked in order to request the partition ID and date, and these will be written to the resource.
