bolkedebruin opened a new pull request, #34729:
URL: https://github.com/apache/airflow/pull/34729
This adds Airflow FS, which is a generic abstraction on top of a filesystem
or object storage. The idea is that you can do the following
```python
import airflow.io.fs as afs
afs.mount("s3://warehouse", "/mnt/warehouse")
afs.mount("file:///tmp", "/mnt/tmp")
@task
def load_file(src):
with afs.open(src) as f:
f.read()
# you can use it the same way in an operator
```
Standard python file operations work (e.g. see shutil.copyfileobj in the
generic FileTransferOperator).
As this is based on `fsspec`, any objectstorage or filesystem implementing
fsspec is supported. For now s3, gcs, adl and local file systems are supported.
There are options for e.g. webhdfs.
As fsspec brings a key/value mapper it can be used as a XCom backend in the
future. It can also work as a backend for DAGs, so we are not necessarily
dependent on git-sync or the likes any more.
The astro-sdk abstractions, like `load_file` could be build on top.
This is work in progress. The intention is to gather feedback :-)
