All Implemented Interfaces:

public class NestedPartitionedParquetTableLocationKey
extends ParquetTableLocationKey
implements EnterpriseTableLocationKey

A TableLocationKey marking tables stored in a Deephaven Enterprise database in the Parquet format. This class overrides the comparison and equals methods of ParquetTableLocationKey so that equality and order only depend on the column and internal partitions of the location, not the parquet file itself.
