s3rmrf

Overview ¶

s3rmrf: parallel batched DeleteObjects under a single non-empty prefix.

Pipeline:

seed (BFS fanout) -> prefixCh -> [L list workers] -> keyCh ->
[batcher] -> batchCh -> [D delete workers] -> stats

Safety:

• -prefix is required and must be non-empty (no whole-bucket rm).
• Refuses to run if bucket versioning is Enabled (DeleteObject would only insert delete markers, not free storage). Suspended is fine.
• Defaults to dry-run; real deletion requires -yes plus a stdin confirmation of "<bucket>/<prefix>".

Throttling:

• SDK is configured with adaptive retry and a high MaxAttempts so that S3 SlowDown (503) responses are absorbed transparently. Batches that still fail after the retryer exhausts are counted as `throttled`.
