class gravitino.api.rel.partitions.identity_partition.IdentityPartition

Bases: Partition

An identity partition represents a result of identity partitioning. For example, for Hive partition

` PARTITION (dt='2008-08-08',country='us') `

its partition name is “dt=2008-08-08/country=us”, field names are [[“dt”], [“country”]] and values are [“2008-08-08”, “us”].

APIs that are still evolving towards becoming stable APIs, and can change from one feature release to another (0.5.0 to 0.6.0).
