In general, high parity with pyarrow for most data access and management. Most of the Table, ChunkedArray, Array, RecordBatchReader, Schema, and Field methods and behavior should be similar to pyarrow.
An ArrayReader, an abstraction beyond RecordBatchReader to allow a stream of arrow arrays that are not RecordBatches.
Readers and writers for Parquet, Arrow IPC, CSV, and JSON.
Initial compute functions.
Initial Python tests.
Improved documentation, both in the type stubs and in the docs website.
Pyodide wheel support.
