etlantic-s3 (Experimental / Preview)

Version 0.57.0 (lockstep with ETLantic core). S3-compatible object-store connector for ETLantic 0.43. Install when pipelines need Experimental s3 source/sink/storage connectors (fake/CI path supported; live AWS is opt-in and not production-ready). Pin with core.

Maturity: Experimental (Alpha classifier). Payload format today is JSON (not Parquet). Fake multipart staging buffers records and serializes once at prepare/commit.

Install

pip install 'etlantic-s3==0.57.2'
# Live AWS (opt-in later; not required for CI):
# pip install 'etlantic-s3[aws]==0.57.2'
# pip install 'etlantic==0.57.2'

Core dependency: etlantic>=0.57.0. Optional: boto3, pyarrow.

Behavior

  • Without boto3, factories use InMemoryS3Fake (multipart abort + conditional commit-pointer semantics).
  • Immutable data objects; readers resolve only committed pointers.
  • Overwrite/append replace the commit pointer; create/first-write modes keep conditional create (If-None-Match).
  • Publication evidence carries ETag / operation metadata without secret endpoints.
