This section addresses the limitations of the OneFS S3 implementation. It is recommended to take these limitations into consideration when designing an application to work with OneFS S3.
Table 27 shows the details about OneFS S3 limitations.
Feature | Limitation |
Object versioning | OneFS does not support Amazon S3 object versioning. It is recommended to use OneFS SnapshotIQ as an alternative method. |
Object lock | OneFS does not support Amazon S3 object lock. It is recommended to use OneFS SmartLock as an alternative solution to meet compliance requirements. |
Object key delimiter | Starting from OneFS 9.3.0, OneFS supports the following delimiter format:
Delimiter does not contain any slash(“/”), such as “abcd”. Therefore, “/abcd” and “ab/cd” are not valid delimiters. |
Number of buckets | There are 1,000 buckets per user and 40,000 per cluster. |
User-defined metadata |
|
Bucket traversal | An S3 user must traverse or execute permissions on all elements of the path to reach an object in the OneFS directory hierarchy. |
Object size | An object may not exceed 16 TiB, which is aligned with the OneFS file system. |
