GENERAL- GeneralDIMENSION- DimensionFACT- Fact
GENERAL, DIMENSION, FACT -2147483648 <= x <= 214748364710241024Top-level TIMESTAMP field to partition the BigQuery table on. BigQuery allows exactly one partition column per table — use clustering for additional pruning dimensions.
512Time granularity for the partition field. Ignored when no partition field is set. Pick the coarsest granularity that still prunes well: BigQuery caps a table at 10,000 partitions.
HOUR- HOURDAY- DAYMONTH- MONTHYEAR- YEAR
HOUR, DAY, MONTH, YEAR Allow the loader to rebuild this table when its partitioning does not match the configuration. BigQuery cannot change partitioning in place, so this is a one-time full-table rewrite whose cost scales with table size. It no-ops once the partitioning matches, but stays enabled — a later change to the partition field or granularity will rebuild the table again.
