The following compression techniques are implemented:
- Sparse Storage for columns with lots of NULL values
- Float Storage for scientific data
- Integer Compression with a bit-size approach
- Sequence Compression for sequences of integers like IDs (1, 2, 3, 4, 5 ...)
- Dictionary Compression for short strings
- BLOB Zipping and Deduplication for strings longer than 1KiB
