So that discussion is most probably outdated, given that **reason is not speed** but **features**: * compression * ability to express things **impossible in JSON** (binary values, type info) * extensibility (JSON itself and all other binary JSONs are _not_ extensible) However, my main questions are **not about CBOR** support - if I could plug a function of my language's implementation into SQLite, this will be just fine. The main question is how to build indexes on such, and AFAIK in JSON1 such indexes are also not possible.
