The MongrelDB PHP client substitutes malformed UTF-8 instead of rejecting the whole request, and reserves hard errors for values like INF, NAN, and recursive structures that genuinely have no JSON representation.
A JSON column in MongrelDB is a typed column that the engine validates at write time and queries from the inside, so the schema-versus-schemaless argument stops being a binary you have to pick a side of.
A column type is not documentation, it is a promise the storage engine can spend, and MongrelDB's type system covers fixed-width integers, decimal128 money, five flavors of time, sortable UUIDs, native JSON, and typed arrays so the engine can plan bytes instead of guessing at strings.
