Isso-W opened a new pull request, #2275: URL: https://github.com/apache/systemds/pull/2275
This pull request introduces a new framework for column decoding in Apache SystemDS, with the addition of a base class `ColumnDecoder` and several specialized implementations (`ColumnDecoderBin`, `ColumnDecoderComposite`, `ColumnDecoderRecode`,`ColumnDecoderPassthrough` and `ColumnDecoderDummycode`). These changes provide a flexible and extensible structure for decoding encoded data in matrix-to-frame transformations. Below are the most important changes grouped by theme: ### Core Framework for Column Decoding * Added `ColumnDecoder` as an abstract base class to define the structure for decoding operations, including methods for decoding (`columnDecode`), handling sub-range decoding (`subRangeDecoder`), and metadata initialization (`initMetaData`). It also implements `Externalizable` for efficient serialization. ### Current Issues * `ColumnDecoderDummycode` ist not supported yet, as well as the test case `ColumnDecoderMixedMethodsTest` * There are still some issues with `DecoderDummyCode`, it do not work together with `DecoderRecode` -- This is an automated message from the Apache Git Service.
