The Flink API only +appears in the two tiny adapter classes, so moving between Flink versions touches one file. + +### Delivery semantics — at-least-once + +The buffer is flushed on every checkpoint barrier (`snapshotState` / `flush(endOfInput)`), so all +rows observed before a checkpoint are acknowledged by Chalk before that checkpoint completes. On +failure Flink restores the last checkpoint and replays; re-sends are safe because `upload_features` +is a **primary-key upsert** (idempotent). There is no Flink-managed operator state — the in-flight +buffer is transient and simply rebuilt from replayed records. Worst-case upload latency is bounded +by `min(flushInterval, checkpointInterval)`. + +## Build + +Requires JDK 17 (matches `chalk-java`).
