LogDevice, a distributed data store for sequential data, originally developed and currently deployed within Facebook is now available as an open source project. LogDevice offers durability, high availability, and total order of records under failures. It is designed for a variety of workloads, including event streaming, replication pipelines, transaction logs, and deferred work journals. LogDevice comes with a command-line administration tool called LDShell.
We look forward to seeing what the open source community contributes, especially in relation to integration with cloud computing environments, monitoring systems, and configuration management.
