[GitHub] [arrow-adbc] lidavidm opened a new issue, #541: [Format] Add more ingest modes
lidavidm opened a new issue, #541:
URL: https://github.com/apache/arrow-adbc/issues/541
We could add more ingest modes to make things easier on integrations like Polars:
https://github.com/pola-rs/polars/blob/702f72a57a1ab2be796679e4facc0d1957a67cc9/py-polars/polars/dataframe/frame.py#L2951-L2955
```
if_exists : {'append', 'replace', 'fail'}
The insert mode.
'replace' will create a new database table, overwriting an existing one.
'append' will append to an existing table.
'fail' will fail if table already exists.
```
- `fail` is our `CREATE`.
- Our `append` does not create the table; we should document how to do this (try to append, if it fails, try to create).
- `replace` is not supported.
Polars currently maps `replace` to `CREATE` and `append` to `APPEND` but this does not match its documented semantics. We should add `replace` and clarify the documentation.
