## Works today

- Object Container Files, read and write, null / deflate / snappy / zstandard
- A schema-compiled RecordCursor with no per-record allocation
- Iceberg field-ids and OCF metadata survive parsing intact

Checked against fastavro, both directions, across all four codecs

- [parquet](https://magmalake.dev/s/parquet) read · write · every encoding · Arrow out
- [parquet-full](https://magmalake.dev/s/parquet-full) parquet · plus ZSTD, BROTLI and LZ4
- [arrow-mlake](https://magmalake.dev/s/arrow-mlake) Arrow layout · C Data Interface · IPC
- [roaring](https://magmalake.dev/s/roaring) 32/64-bit · deletion vectors
- [Every tin](https://magmalake.dev/tins)
