| Column Name | Data Type | Description |
|---|---|---|
| aster_ccm_id | INTEGER | Optional partition column that the function uses internally. If the input table has this column, the CCM function assumes that the table was output by the CCMPrepare function, which ensures that the CCM function partitions input data across workers consistently over multiple function calls. If the input table omits this column, the CCM function generates it, and partitioning of data across workers is not be consistent over multiple function calls. |
| sequence_id | Any except DOUBLE PRECISION | Identifier of the time sequence. |
| period_id | Any | Identifier of the time period within the time sequence. |
| timeseries_value | Any | Time series values to test for causal relationships. The table can have several such columns. |
