The following standard S3 APIs are supported:
Bucket (HEAD/GET/PUT/DEL) Including ListObjects and ListObjectsV2
Bucket Lifecycle (GET/PUT/DEL)
Bucket Policy (GET/PUT/DEL)
Bucket Tagging (GET/PUT/DEL)
Object (GET/PUT/DEL)
Object Tagging (GET/PUT/DEL)
Object Multiparts (POST Create/Complete, GET/DEL/PUT, GET Parts)
Bucket names must be between 3 and 63 characters long.
Bucket names can consist only of lowercase letters, numbers, dots (.), and hyphens (-).
Bucket names must begin and end with a letter or number.
Bucket names must not be formatted as IP addresses (for example, 192.168.5.4).
Bucket names must be unique across the cluster.
Object key names must be up to 1024 characters long.
The prefix /
of an object is interpreted as a directory, and such directory segments are limited to 255 characters.
See AWS S3 object name limitations. Match them to limitations in other protocols.
Note: It is recommended to avoid special characters that might be unsupported using protocols other than S3.
The S3 protocol implementation supports the following policy actions:
s3:*
Note: this wildcard is supported for IAM policies but not for bucket policies
s3:AbortMultipartUpload
s3:CreateBucket
s3:DeleteBucket
s3:DeleteBucketPolicy
s3:DeleteObject
s3:GetBucketLocation
s3:GetLifecycleConfiguration
s3:PutLifecycleConfiguration

s3:GetBucketPolicy
s3:GetObject
s3:ListAllMyBuckets
s3:ListBucket
s3:PutBucketPolicy
s3:PutObject
s3:GetBucketTagging
s3:PutBucketTagging
Weka supports the AWS S3 Lifecycle Configuration elements and definitions, with the limitation of only supporting the lifecycle Expiration
action.
