Enterprise serialization formats for xwsystem - Parquet, Avro, HDF5, NetCDF, and 14 more heavyweight formats

Project description

xwformats

Advanced serialization formats in one package. Schema (Protobuf, Avro, Parquet, …), scientific (HDF5, Feather, Zarr, …), database (LMDB, LevelDB, …), binary and text. Same API as xwsystem; auto-registers with codec registry on import. Lite / lazy / full install.

Install

Install What you get When to use
pip install exonware-xwformats Lite — core + xwsystem only Minimal footprint; you add formats as needed.
pip install exonware-xwformats[lazy] Lazy — missing format deps install on first use Development; optional formats without pre-installing everything.
pip install exonware-xwformats[full] Full — common format deps pre-installed Production or CI when you want all formats up front.

Requires exonware-xwsystem. Same package; [lazy] and [full] are extras.


Quick start

from exonware.xwformats import XWFormats

xf = XWFormats()
print(xf.list_formats())                       # All registered formats
data = xf.convert(json_bytes, "json", "yaml")  # Bidirectional conversion
ser = xf.get_serializer("parquet")
ser.encode(value)
ser.decode(data)

Importing xwformats registers its formats with xwsystem; use xwsystem's codec/facade for auto-detection by file extension. See REF_14_DX and REF_15_API.


What you get

Area What's in it
Schema Protobuf, Avro, Parquet, Thrift, ORC, Cap'n Proto, FlatBuffers, Arrow.
Scientific HDF5, Feather, Zarr, NetCDF, MAT.
Database LMDB, LevelDB, RocksDB, GraphDB.
Binary / text BSON, UBJSON; CSV, YAML, TOML, XML, RON.
Integration Same converter/facade as xwsystem; auto-registration with codec registry on import.

Lite = minimal deps. Lazy = optional format deps install on first use. Full = common optionals pre-installed. Platform notes (e.g. RocksDB on Windows) in docs/logs/setup/. Known issues: docs/_archive/KNOWN_ISSUES.md and REF_22_PROJECT.md.
