### Partition clause

BigQuery supports the use of a [partition by](https://cloud.google.com/bigquery/docs/data-definition-language#specifying_table_partitioning_options) clause to easily partition a <Term id="table" /> by a column or expression. This option can help decrease latency and cost when querying large tables. Note that partition pruning [only works](https://cloud.google.com/bigquery/docs/querying-partitioned-tables#pruning_limiting_partitions) when partitions are filtered using literal values (so selecting partitions using a <Term id="subquery" /> won't improve performance).
