One can also add a pipeline or ParallelTask as initial / final node

not really: there are places which expect a task, at least I had places where intelij complained that a method wasn't available

Looks very good otherwise. Please squash.
Let's wait with a release for the other PR

I'd think the parameter s3_url should be called s3_uri, according to the cp command. An URL is always an URI, but not all URIs are URLs. See as well wikipedia URL

@jankatins is this running in production? |

@martin-loetzsch Nope, should also be integrated into https://github.com/mara/mara-storage where this looks much easier to do. |

Refactors the file reader and adds s3 file reader as an alternative to local file reads.
New commands:
data_integration.parallel_tasks.files.ParallelReadS3File: reads in a whole bucketdata_integration.commands.files.ReadS3File: reads a single file from S3From initial testing, this is a lot slower than sync + reading from a local file system (both iterating over the bucket to get the file list and the individual reads...) but then syncing that bucket to a local filesystem is also taking time... From my perspective this is only worth it if you have to do a "sync to local" every time (which we have to do, not volumns in our ETL container :-(), so the second run is then saving time compared to doing a sync + incremental read via file system. That's at least the theory, up to now I only tested locally.
The single file read will also come in handy as a replacement of google sheet imports.
