IDWT2D Output Table Schema
The table has reconstructed sequences.
|partition_column||Same as in input table||[Column appears once for each specified partition_column.] Identifier of sequence to which data belongs. Rows with same partition column values belong to same sequence.
If InputTable has multiple partition columns, first one is distribution key in both InputTable and OutputTable.
If InputTable has only one partition column, OutputTable has as its distribution key a function-created column named dwt_id_random_name. Every cell of dwt_id_random_name has the value 1.
|indexy||INTEGER||Y index of reconstructed matrix.|
|indexx||INTEGER||X index of reconstructed matrix.|
|target_column||INTEGER, SMALLINT, BIGINT, DOUBLE PRECISION, or NUMERIC||[Column appears once for each target_column.] Reconstructed matrix.|
