Status update: Many methods that operate sequentially on the original mapping have been implemented using partial on the fly decoding of the compressed LZW mapping via an iterator. Methods with more complex or non sequential access patterns are not yet handled in this way (for example leftMultByMatrixNoPreAgg) and currently fall back to DDC. These will be addressed in follow-up work. Most decompression paths now rely on partial decoding of the LZW mapping rather than full materialization. Scalar and unary operations have also been implemented. Several previously reported issues have been fixed. I have reverted the unintended formatting changes in the affected files and ensured alignment with the existing code style. I will continue working on the remaining improvements suggested by @Baunsgaard and @janniklinde. What is still missing at this point are more dedicated tests for the individual methods to ensure correctness. Thanks for the detailed feedback and reviews, they were very helpfull! -- This is an automated message from the Apache Git Service.
