usecases only where the setup is using bucket versioning or with replicated buckets, use this feature to optimize versioning behavior for some specific applications. MinIO experts will evaluate and guide on the benefits for your application, please reach out to us on <https://subnet.min.io>.**

Spark/Hadoop workloads which use Hadoop MR Committer v1/v2 algorithm upload objects to a temporary prefix in a bucket. These objects are 'renamed' to a different prefix on Job commit. Object storage...

func getAvailablePoolIdx(ctx context.Context) int {
        serverPools := z.getServerPoolsAvailableSpace(ctx)
        total := serverPools.TotalAvailable()
        // choose when we reach this many
        choose := rand.Uint64() % total

                atTotal += pool.Available

lead to conflicts and the patch will not cleanly apply. Conflicts might be trivial which can be resolved easily, when conflicts seem to be non-trivial or touches the part of the code-base the developer is not confident - to get additional clarity reach out to #hack on MinIOHQ slack channel. Hasty changes must be avoided, minor fixes and logs may be added to hotfix branches but this should not be followed as practice.*

Once the **patch** is successfully applied, developer must run tests to...

### Verify auto-encryption

> Note that auto-encryption only affects requests without S3 encryption headers. So, if a S3 client sends
> e.g. SSE-C headers, MinIO will encrypt the object with the key sent by the client and won't reach out to
> the configured KMS.

To verify auto-encryption, use the following `mc` command:

```
mc cp test.file myminio/bucket/
