  "message": "fix: no panic on empty partition in register_record_batches (#1627)\n\n* fix: no panic on empty partition in register_record_batches\n\n`register_record_batches` read the schema via unchecked `partitions.0[0][0]`,\nwhich panics when a partition contains no record batches (e.g. the batches of\nan empty pyarrow table, whose `to_batches()` returns `[]`).\n\nTake the schema from the first available batch across all partitions and return\na clear error when there is none, mirroring the empty-table handling added for\n`from_arrow_table` in #613. A non-empty later partition now also works instead\nof panicking on an empty leading one.\n\nCo-Authored-By: Claude Opus 4.8 (1M context) \u003cnoreply@anthropic.com\u003e\n\n* refactor: address review feedback\n\n- Use find_map(|p| p.first()) instead of flatten().next() to make the\n  \"first batch in any partition\" intent clearer (per @kosiew).\n- Extend regression test to also assert the empty outer partition list\n  case ([]) raises the same ValueError.\n\nCo-Authored-By: Claude Opus 4.8 (1M context) \u003cnoreply@anthropic.com\u003e\n\n---------\n\nCo-authored-by: Claude Opus 4.8 (1M context) \u003cnoreply@anthropic.com\u003e",
