We are pleased to announce the alpha release of Mountpoint for Amazon S3, a new open source file client that delivers high throughput access, lowering compute costs for data lakes on Amazon S3. Mountpoint for Amazon S3 is a file client that translates local file system API calls to S3 object API calls like GET and LIST. It is ideal for read-heavy data lake workloads that process petabytes of data and need Amazon S3’s high elastic throughput to scale up and down across thousands of instances.

Mountpoint for Amazon S3 supports random and sequential read operations on files, and listing files and directories. For details on supported file system operations with this release, read the documentation.

Mountpoint for Amazon S3 is an open source project. We are making the alpha release of Mountpoint for Amazon S3 available to the community to collect feedback early and incorporate your input into the design and implementation. We welcome your contributions and your feedback on our roadmap which outlines the plan for adding additional features to Mountpoint for Amazon S3.
