object-store: remove S3ConditionalPut::ETagPutIfNotExists #6802
Conversation
As of today [0] S3 now supports the If-Match for in-place conditional
writes. This commit adjusts the existing support for
S3ConditionalPut::Etag mode for compatibility with real S3's particular
semantics, which vary slightly from MinIO and R2. Specifically:
* Real S3 can occasionally return 409 Conflict when concurrent
If-Match requests are in progress. These requests need to be
retried.
* Real S3 returns 404 Not Found instead of 412 Precondition Failed
when issuing an If-Match request against an object that does not
exist.
Fix apache#6799.

Now that real S3 supports `If-Match`, we no longer need this special conditional put mode for real S3.

As written in #6799 (comment), the feature is now available in the I've given a try to this branch with the flag enabled and it worked for me locally, might be worth trying it out. Thanks a lot for the tests, they're always great to run locally! 🙏 |

Yes, just bumped to the Give me a holler when 4.0.3 is released—I'll try to keep an eye on it myself—so that I can update this PR to use it. And then we should be ready to merge. |

Now that real S3 supports
If-Match, we no longer need this special conditional put mode for real S3.Considerations:
If-Match(which doesn't yet exist). @bentsku mentioned he'd try to add support to localstack later this week. See S3 Put IfMatch #6799 (comment).Which issue does this PR close?
Cleanup related to #6799.
Are there any user-facing changes?
The removal of
S3ConditionalPut::ETagPutIfNotExistswould be user facing, but this variant has not yet made it into a release.cc @tustvold
