InputTable Schema

Column Data Type Description
ccm_id INTEGER [Optional] Partition column that function uses internally.

If the table has this column, the CCM function assumes that the table was output by the CCMPrepare (ML Engine) function, which ensures that the CCM function partitions input data across workers consistently over multiple function calls.

If InputTable omits this column, the CCM function creates it, and partitioning of data across workers might vary over multiple function calls.

sequence_id Any except DOUBLE PRECISION Time sequence identifier.
period_id Any Identifier of time period within time sequence.
timeseries_value Any [Column appears one or more times.] Time series value to test for potential causal relationships.
