About this resource

Purpose: comprehensive, machine-readable information about the Arpeio ADBC drivers — wire-protocol drivers for SQL Server, PostgreSQL and Oracle that return Apache Arrow RecordBatches.

Format: JSON files following JSON Schema Draft 2020-12, with rich semantic metadata.

Use cases: RAG systems, AI assistants, automated documentation, search engines, developer tools.

  • Protocols: MS-TDS 7.4, Frontend/Backend v3, TNS + TTC, DRDA (in development)
  • Result format: Apache Arrow RecordBatches — zero-copy into pandas, Polars, DuckDB and Spark
  • Runtime dependencies: OpenSSL only, beyond libc
  • Platforms: Linux (x64), Windows (x64); macOS staged, not yet published
  • ADBC clients: Python, C/C++, C# / .NET, Go, Java, R, Rust
  • Licensing: binaries free on public GitHub Releases, licence-gated at runtime
