Arrow.Json.Writer (Arrow v0.1.0)

Copy Markdown

Emits Arrow integration test JSON form from in-memory Arrow.Schema and Arrow.RecordBatch structs.

The output is a plain Elixir map / list shape suitable for Jason.encode/1. Numeric types whose range can exceed JSON's 2^53 limit (Int64, UInt64, Date64, Timestamp) are written as decimal strings, matching the reference C++ writer. Binary columns are written as uppercase hex strings.
