Alluxio supports a RESTful API that is compatible with the basic operations of the Amazon S3 API .
The Alluxio S3 API should be used by applications designed to communicate with an S3-like storage and would benefit from the other features provided by Alluxio, such as data caching, data sharing with file system based applications, and storage system abstraction (e.g., using Ceph instead of S3 as the backing store). For example, a simple application that downloads reports generated by analytic tasks can use the S3 API instead of the more complex file system API.
Limitations and Disclaimers
Alluxio Filesystem Limitations
Only top-level Alluxio directories are treated as buckets by the S3 API.
Hence the root directory of the Alluxio filesystem is not treated as an S3 bucket. Any root-level objects (eg: alluxio://file
) will be inaccessible through the Alluxio S3 API.
To treat sub-directories as a bucket, the separator :
must be used in the bucket name (eg: s3://sub:directory:bucket/file
).
Note that this is purely a convenience feature and hence is not returned by API Actions such as ListBuckets.
Alluxio uses /
as a reserved separator. Therefore, any S3 paths with objects or folders named /
(eg: s3://example-bucket//
) will cause undefined behavior. For additional limitations on object key names please check this page: Alluxio limitations
No Bucket Virtual Hosting
Virtual hosting of buckets is not supported in the Alluxio S3 API. Therefore, S3 clients must utilize path-style requests (i.e: http://s3.amazonaws.com/{bucket}/{object}
and NOT http://{bucket}.s3.amazonaws.com/{object}
).
S3 Writes Implicitly Overwrite
As described in the AWS S3 docs for PutObject :
Amazon S3 is a distributed system. If it receives multiple write requests for the same object simultaneously, it overwrites all but the last object written. Amazon S3 does not provide object locking; if you need this, make sure to build it into your application layer or use versioning instead.
Note that at the moment the Alluxio S3 API does not support object versioning
Alluxio S3 will overwrite the existing key and the temporary directory for multipart upload.
Folders in ListObjects(V2)
All sub-directories in Alluxio will be returned in ListObjects(V2) as 0-byte folders. This behavior is in accordance with if you used the AWS S3 console to create all parent folders for each object.
Tagging & Metadata Limits
User-defined tags on buckets & objects are limited to 10 and obey the S3 tag restrictions .
Set the property key alluxio.proxy.s3.tagging.restrictions.enabled=false
to disable this behavior.
The maximum size for user-defined metadata in PUT-requests is 2KB by default in accordance with S3 object metadata restrictions .
Set the property key alluxio.proxy.s3.header.metadata.max.size
to change this behavior.
Performance Implications
The S3 API leverages the Alluxio REST proxy , introducing an additional network hop for Alluxio clients. For optimal performance, it is recommended to run the proxy server and an Alluxio worker on each compute node. It is also recommended to put all the proxy servers behind a load balancer.

Property Keys
The following table contains the configurable Alluxio property keys which pertain to the Alluxio S3 API.
Property Name
Default
Description
alluxio.proxy.s3.bucket.naming.restrictions.enabled
Toggles whether or not the Alluxio S3 API will enforce AWS S3 bucket naming restrictions. See https://docs.aws.amazon.com/AmazonS3/latest/userguide/bucketnamingrules.html.
alluxio.proxy.s3.bucketpathcache.timeout
Expire bucket path statistics in cache for this time period. Set 0min to disable the cache. If enabling the cache, be careful that Alluxio S3 API will behave differently from AWS S3 API if bucket path cache entries become stale.
alluxio.proxy.s3.complete.multipart.upload.keepalive.enabled
Whether or not to enabled sending whitespace characters as a keepalive message during CompleteMultipartUpload. Enabling this will cause any errors to be silently ignored. However, the errors will appear in the Proxy logs.
alluxio.proxy.s3.complete.multipart.upload.keepalive.time.interval
The complete multipart upload maximum keepalive time. The keepalive whitespace characters will be sent after 1 second, exponentially increasing in duration up to the configured value.
alluxio.proxy.s3.complete.multipart.upload.min.part.size
The minimum required file size of parts for multipart uploads. Parts which are smaller than this limit aside from the final part will result in an EntityTooSmall error code. Set to 0 to disable size requirements.
alluxio.proxy.s3.complete.multipart.upload.pool.size
The complete multipart upload thread pool size.
alluxio.proxy.s3.deletetype
Delete type when deleting buckets and objects through S3 API. Valid options are ALLUXIO_AND_UFS
(delete both in Alluxio and UFS), ALLUXIO_ONLY
(delete only the buckets or objects in Alluxio namespace).
alluxio.proxy.s3.global.read.rate.limit.mb
Limit the maximum read speed for all connections. Set value less than or equal to 0 to disable rate limits.
alluxio.proxy.s3.header.metadata.max.size
The maximum size to allow for user-defined metadata in S3 PUTrequest headers. Set to 0 to disable size limits.
alluxio.proxy.s3.multipart.upload.cleaner.enabled
Enable automatic cleanup of long-running multipart uploads.
alluxio.proxy.s3.multipart.upload.cleaner.pool.size
The abort multipart upload cleaner pool size.
alluxio.proxy.s3.multipart.upload.cleaner.retry.count
The retry count when aborting a multipart upload fails.
alluxio.proxy.s3.multipart.upload.cleaner.retry.delay
The retry delay time when aborting a multipart upload fails.
alluxio.proxy.s3.multipart.upload.cleaner.timeout
The timeout for aborting proxy s3 multipart upload automatically.
alluxio.proxy.s3.single.connection.read.rate.limit.mb
Limit the maximum read speed for each connection. Set value less than or equal to 0 to disable rate limits.
alluxio.proxy.s3.tagging.restrictions.enabled
Toggles whether or not the Alluxio S3 API will enforce AWS S3 tagging restrictions (10 tags, 128 character keys, 256 character values) See https://docs.aws.amazon.com/AmazonS3/latest/userguide/tagging-managing.html.

Example Usage
S3 API Actions
AWS CLIYou can use the AWS command line interface to send S3 API requests to the Alluxio S3 API. Note that you will have to provide the --endpoint
parameter to specify the location of the Alluxio S3 REST API with the server's base URI included (i.e: --endpoint "http://{alluxio.proxy.web.hostname}:{alluxio.proxy.web.port}/api/v1/s3/"
).
As a pre-requisite for operations which involve the Authorization
header you may need to configure AWS credentials .
Copy $ aws configure --profile alluxio-s3
AWS Access Key ID [None]: {user}
AWS Secret Access Key [None]: {dummy value}
Default region name [None]:
Default output format [None]:
REST ClientsYou can directly use any HTTP client to send S3 API requests to the Alluxio S3 API. Note that the base URI for the Alluxio S3 API's REST server is /api/v1/s3/
(i.e: your requests should be directed to "http://{alluxio.proxy.web.hostname}:{alluxio.proxy.web.port}/api/v1/s3/"
).
At the moment, access key and secret key validation does not exist for the Alluxio S3 API. Therefore the Authorization header is used purely to specify the intended user to perform a request. The header follows the AWS Signature Version 4 format.
Copy $ curl -i -H "Authorization: AWS4-HMAC-SHA256 Credential=testuser/... SignedHeaders=... Signature=..." ...

Python S3 Client
Tested for Python 2.7.
Create a connection:
Please note you have to install boto package first.
Copy import boto
import boto . s3 . connection
conn = boto . connect_s3 (
aws_access_key_id = '' ,
aws_secret_access_key = '' ,
host = 'localhost' ,
port = 39999 ,
path = '/api/v1/s3' ,
is_secure = False ,
calling_format = boto.s3.connection. OrdinaryCallingFormat (),
)
Authenticating as a user:
By default, authenticating with no access_key_id uses the user that was used to launch the proxy as the user performing the file system actions.
Set the aws_access_key_id
to a different username to perform the actions under a different user.
Create a bucket
Copy bucketName = 'bucket-for-testing'
bucket = conn . create_bucket (bucketName)
List all buckets owned by the user
Authenticating as a user is necessary to have buckets returned by this operation.
Copy conn = boto . connect_s3 (
aws_access_key_id = 'testuser' ,
aws_secret_access_key = '' ,
host = 'localhost' ,
port = 39999 ,
path = '/api/v1/s3' ,
is_secure = False ,
calling_format = boto.s3.connection. OrdinaryCallingFormat (),
)
conn . get_all_buckets ()
PUT a small object
Copy smallObjectKey = 'small.txt'
smallObjectContent = 'Hello World!'
key = bucket . new_key (smallObjectKey)
key . set_contents_from_string (smallObjectContent)
Get the small object
Copy assert smallObjectContent == key . get_contents_as_string ()
Upload a large object
Create a 8MB file on local file system.
Copy $ dd if = /dev/zero of = 8mb.data bs = 1048576 count = 8
Then use python S3 client to upload this as an object
Copy largeObjectKey = 'large.txt'
largeObjectFile = '8mb.data'
key = bucket . new_key (largeObjectKey)
with open (largeObjectFile, 'rb' ) as f :
key . set_contents_from_file (f)
with open (largeObjectFile, 'rb' ) as f :
largeObject = f . read ()
Get the large object
Copy assert largeObject == key . get_contents_as_string ()
Delete the objects
Copy bucket . delete_key (smallObjectKey)
bucket . delete_key (largeObjectKey)
Initiate a multipart upload
Copy mp = bucket . initiate_multipart_upload (largeObjectKey)
Upload parts
Copy import math , os
from filechunkio import FileChunkIO
# Use a chunk size of 1MB (feel free to change this)
sourceSize = os . stat (largeObjectFile). st_size
chunkSize = 1048576
chunkCount = int (math. ceil (sourceSize / float (chunkSize)))
for i in range (chunkCount):
offset = chunkSize * i
bytes = min (chunkSize, sourceSize - offset)
with FileChunkIO (largeObjectFile, 'r' , offset = offset, bytes = bytes ) as fp :
mp . upload_part_from_file (fp, part_num = i + 1 )
Complete the multipart upload
Abort the multipart upload
Non-completed uploads can be aborted.
Delete the bucket
Copy bucket . delete_key (largeObjectKey)
conn . delete_bucket (bucketName)
