|
|
|
|
| Item | Specification |
|

|
|
| Maximum number of objects per bucket | no-limit |
|
|
| Maximum object size | 50 TiB |
|
|
| Minimum object size | 0 B |
|
|
| Maximum object size per PUT operation | 5 TiB |
|
|
| Maximum number of parts per upload | 10,000 |
|
|
| Part size range | 5 MiB to 5 TiB. Last part can be 0 B to 5 TiB |

|
| Maximum number of parts returned per list parts request | 10000 |
|
|
| Maximum number of objects returned per list objects request | 1000 |
|
|
| Maximum number of multipart uploads returned per list multipart uploads request | 1000 |
|
|
| Maximum length for bucket names | 63 |
|
|
| Maximum length for object names | 1024 |
|
|
| Maximum length for '/' separated object name segment | 255 |
|
|
| Maximum number of versions per object | 10000 (can be configured to higher values but we do not recommend beyond 10000) |
|
|
|
|
> NOTE: While MinIO does not implement an upper boundary on buckets, your cluster's hardware has natural limits that depend on the workload and its scaling patterns. We strongly recommend [MinIO SUBNET](https://min.io/pricing) for architecture and sizing guidance for your production use case.

## 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 consider opening a [GitHub issue](https://github.com/minio/minio/issues) with relevant details on why MinIO must implement them.
|
|
|
|
### List of Amazon S3 Bucket API's not supported on MinIO
|
|
|
|
- BucketACL (Use [bucket policies](https://min.io/docs/minio/linux/administration/identity-access-management/policy-based-access-control.html) instead)
|
|
- BucketCORS (CORS enabled by default on all buckets for all HTTP verbs, you can optionally restrict the CORS domains)
|
|
- BucketWebsite (Use [`caddy`](https://github.com/caddyserver/caddy) or [`nginx`](https://www.nginx.com/resources/wiki/))
|
|
- BucketAnalytics, BucketMetrics, BucketLogging (Use [bucket notification](https://min.io/docs/minio/linux/administration/monitoring/bucket-notifications.html) APIs)
|
|
|
|
### List of Amazon S3 Object API's not supported on MinIO
|
|
|
|
- ObjectACL (Use [bucket policies](https://min.io/docs/minio/linux/administration/identity-access-management/policy-based-access-control.html) instead)
|
|
|
|
## Object name restrictions on MinIO
|
|
|
|
- Object name restrictions on MinIO are governed by OS and filesystem limitations. For example object names that contain characters `^*|\/&";` are unsupported on Windows platform or any other file systems that do not support filenames with special charaters.
|
|
|
|
> **This list is non exhaustive, it depends on the operating system and filesystem under use - please consult your operating system vendor for a more comprehensive list of special characters**.
|
|
|
|
MinIO recommends using Linux operating system for production workloads.
|
|
|
|
- Objects must not have conflicting objects as parent objects, applications using this behavior should change their behavior and use non-conflicting unique keys, for example situations such as following conflicting key patterns are not supported.
|
|
|
|
```
|
|
PUT <bucketname>/a/b/1.txt
|
|
PUT <bucketname>/a/b
|
|
```
|
|
|
|
```
|
|
PUT <bucketname>/a/b
|
|
PUT <bucketname>/a/b/1.txt
|
|
```
