Breaking Changes

●Issue #1

The Rust implementation of `create_table()` and `Table.add()` now accepts `RecordBatch` or `Vec<RecordBatch>` as input, which may break existing calls expecting different types.

Migration Steps

  1. 1
    Review calls to `create_table()` and `Table.add()` in Rust code to ensure they correctly pass `RecordBatch` or `Vec<RecordBatch>` if they were previously passing other types.

Release Summary

This release introduces significant features like expression builder API, parallel inserts, and improved remote table handling, alongside breaking changes in Rust input types for table creation and additions.
