### List of Amazon S3 API's not supported on Minio
We found the following APIs to be redundant or less useful outside of AWS S3. If you have a different view on any of the APIs we missed, please open a [github issue](https://github.com/minio/minio/issues).

#### List of Amazon S3 Bucket API's not supported on Minio

- BucketACL (Use [bucket policies](https://docs.minio.io/docs/minio-client-complete-guide#policy) instead)
- BucketCORS (CORS enabled by default on all buckets for all HTTP verbs)
- BucketLifecycle (Not required for Minio erasure coded backend)
- BucketReplication (Use [`mc mirror`](https://docs.minio.io/docs/minio-client-complete-guide#mirror) instead)
- BucketVersions, BucketVersioning (Use [`s3git`](https://github.com/s3git/s3git))
- BucketWebsite (Use [`caddy`](https://github.com/mholt/caddy) or [`nginx`](https://www.nginx.com/resources/wiki/))
- BucketAnalytics, BucketMetrics, BucketLogging (Use [bucket notification](https://docs.minio.io/docs/minio-client-complete-guide#events) APIs)
- BucketRequestPayment
- BucketTagging

#### List of Amazon S3 Object API's not supported on Minio

- ObjectACL (Use [bucket policies](https://docs.minio.io/docs/minio-client-complete-guide#policy) instead)
- ObjectTorrent
- ObjectVersions

### Object name restrictions on Minio
Object names that contain characters `^*|\&#34; are unsupported on Windows and other file systems which do not support filenames with these characters.

Add large bucket support for erasure coded backend (#5160) This PR implements an object layer which combines input erasure sets of XL layers into a unified namespace. This object layer extends the existing erasure coded implementation, it is assumed in this design that providing > 16 disks is a static configuration as well i.e if you started the setup with 32 disks with 4 sets 8 disks per pack then you would need to provide 4 sets always. Some design details and restrictions: - Objects are distributed using consistent ordering to a unique erasure coded layer. - Each pack has its own dsync so locks are synchronized properly at pack (erasure layer). - Each pack still has a maximum of 16 disks requirement, you can start with multiple such sets statically. - Static sets set of disks and cannot be changed, there is no elastic expansion allowed. - Static sets set of disks and cannot be changed, there is no elastic removal allowed. - ListObjects() across sets can be noticeably slower since List happens on all servers, and is merged at this sets layer.
