We are extremely excited to announce the release of Alluxio 2.1.0!
This release contains a variety of improvements ranging from user experience, bugfixes, and major performance improvements. A list of changes can be found below.
Alluxio Structured Data Service
This release includes a new Alluxio subsystem for managing and transforming structured data. Structured data comes in the form of databases, tables, and partitions. It is the backbone of many companies’ analytics systems.
Alluxio is entering this space in order to provide performance improvements more than just raw I/O. With this release a simple command can transform data in raw formats (such as CSV) into Parquet files, a much more compact and performant file format which is more suitable for running queries on systems such as Presto.
Additionally, the release artifacts now include a Presto connector which can be used to connect your Presto cluster to Alluxio.
Kubernetes Helm Chart Deployment
Thanks to community contributions, and a special thanks to the Alibaba Cloud Kubernetes Team a more robust set of Kubernetes templates as well as a helm chart for Kubernetes deployment is now included with Alluxio. Thanks to the team and Alluxio maintainers for this great improvement! Read more about how to use Helm Chart to deploy Alluxio in the Kubernetes environment
Support for Google Dataproc
A public Google Dataproc init action is now available for users to deploy Alluxio with Google Cloud. Read more about how to deploy Alluxio with Google Dataproc in the documentation.
Reduction of Default Block Size
In this release the default block size in Alluxio has been reduced from 512MB to 64MB. By decreasing the block size, evictions on workers will evict lesser-used data with finer granularity. This can improve use cases where the block size is relatively large compared to the block size of files.
