Searchable compression for JSON – ~99% page skip and sub-ms lookups2025 · github.com · ▲15Problem JSON/NDJSON is everywhere in data platforms, but compression usually breaks searchability. You either keep queryable raw stores (high I/O/egress) or compress into gz/zstd blobs (cheap to store, painful to probe). The “cloud tax” shows up as wasted reads. What I built (SEE — Semantic Entropy Encoding) A schema-aware, searchable compression codec for JSON that keeps exists/pos lookups fast while still compressing. Internals: structure-aware delta + dictionaries, a PageDir + mini-index to jump to relevant pages, and a tuned Bloom filter that skips ~99% of pages.…

I've been a longtime member @ HN, but I haven't been a developer. In fact, my only HN submission has been one asking how to learn to code (http://news.ycombinator.com/item?id=820741). My cofounder and I decided to solve the problem by making a simple, interactive way to get started with Codecademy. We'd love your feedback. If you're interested in helping us to get more courses up (on any topic!), please send us an email at [email protected].
