データ形式について言えば、chDBはClickHouseと100%機能互換です。
|
||
|
||
入力形式は、`File`、`URL`、または`S3`のようなファイル対応テーブルへの`INSERT`および`SELECT`に提供されるデータを解析するために使用されます。出力形式は、`SELECT`の結果を整理し、ファイル対応テーブルへの`INSERT`を実行するために使用されます。ClickHouseがサポートするデータ形式に加えて、chDBも以下をサポートしています：
|
||
|
||
- 出力形式としての`ArrowTable`、タイプはPythonの`pyarrow.Table`
|
||
- 入力および出力形式としての`DataFrame`、タイプはPythonの`pandas.DataFrame`。例については、[test_joindf.py](https://github.com/chdb-io/chdb/blob/main/tests/test_joindf.py)をご参照ください。
|
||
- 出力としての`Debug`（`CSV`のエイリアスとして）、ただしClickHouseからのデバッグ冗長出力を有効にしています。
|
||
|
||
ClickHouseがサポートするデータ形式は以下の通りです：
