What is the “guarantee” of Airbyte data extraction?

  • At least once
  • At most once
  • Exactly once

Hey @datayoshi,
Great question!
The current guarantee is at least once.
Partial failure can lead to duplicates and we consider that the most important is to have exhaustive raw data and that cleaning can happen downstream or via our Incremental Dedupe normalization.
