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
    If you were relying on the previous input types for `create_table()` or `Table.add()` in Rust, update them to use `RecordBatch` or `Vec<RecordBatch>`.
