We are excited to announce the release of Alluxio v1.6.0. This release provides significant usability improvements. The biggest feature for this release is the S3 API, which allows applications to interact with Alluxio in the same way that they interact with S3. Highlights for the release are listed below.
Downloads for this release can be found here: Downloads
S3 API
1.6.0 adds support for a RESTful API that is compatible with the basic operations of the Amazon S3 API. Applications previously using S3 as a backend can be seamlessly transitioned to use Alluxio backed by S3 (or any other storage) without code change. See the documentation for more details.
Python Client
A Python Client has been developed for interacting with Alluxio from Python environments. The Python client exposes an API similar to the native Java API. See this example of how to perform basic filesystem operations in Alluxio.
Audit Logging
Alluxio supports audit logging of user accesses. With audit logging, system administrators can keep track of which operations each user has attempted to perform. The format and functionality is consistent with HDFS audit logging. See the documentation for more details
Third party UFS connector management
1.6.0 improves UFS extensibility by enabling users to write their own UFS extension JARs and then add them to Alluxio at runtime. See the Using Under Storage Extensions and Developing Under Storage Extensions docs for more details.
Dynamically adjustable log levels
Users can now modify Alluxio server log levels without needing to restart the server. For example, to get debug logging for the “alluxio.master.file” logger, you could run
alluxio logLevel –loggerName=alluxio.master.file –target=master_ip:19999 –level=DEBUG
See the documentation for more details.
Remote Logging
Alluxio supports sending logs to a remote log server over the network. This feature can be useful to system administrators who want to consolidate Alluxio logs in a central location. See the documentation for more details.
