I think one of the important things we should do for this blog is to produce some performance charts to compare ALP Specifically I think we should 1. Pick representative data sets (also we should find one that has actual floating point data that ALP doesn't work for) 2. Encoding/compression: PLAIN encoding + no compression, PLAIN Encoding + zstd, ALP 4. For each data set, for each compression comparison, report (compression speed (GB/s), decompression speed (GB/s), and compressed size (bits/value)) We can follow the model of the original paper, but compare against existing parquet encodings, not other techniques https://ir.cwi.nl/pub/33334/33334.pdf <img width="384" height="512" alt="Screenshot 2026-08-07 at 9 30 45 AM" src="https://github.com/user-attachments/assets/ecaded7a-edd5-4bc1-bc5a-7053bb7efd20" /> <img width="364" height="247" alt="Screenshot 2026-08-07 at 9 30 54 AM" src="https://github.com/user-attachments/assets/24b6e709-187f-4654-a84b-434eed54a2cf" /> -- This is an automated message from the Apache Git Service.
