microsoft/FASTER

FASTER is a high-performance, concurrent key-value store and append-only log engine designed for low-latency data access. It features a hybrid log architecture that separates hot in-memory data from cold disk-backed storage, supporting both synchronous and asynchronous operations with configurable concurrency control. The system provides robust state management through pluggable checkpointing, recovery, and log compaction, while also offering remote client-server communication and publish/subscribe messaging capabilities.

This period focused on modernizing the C++ and C# codebases, including upgrading to C++17/.NET 7 and refactoring the device and I/O layers for improved scalability. The team introduced a new F2 key-value store architecture with hot/cold index separation and added comprehensive YCSB benchmarks to evaluate performance. Additionally, legacy C# playgrounds and Windows-specific native libraries were removed to streamline the project.

28 changes

This period focused on the introduction of the FASTER v2 API, featuring asynchronous operations, manual locking, and a modular state machine for synchronization. It also established a pluggable checkpoint and recovery infrastructure and added support for variable-length types and Azure Blob storage as a persistent backend.

19 changes

This period focused on introducing a remote client-server architecture for FASTER, including C# and JavaScript client libraries, server-side session handling, and pub/sub messaging. It also added comprehensive benchmarking, stress testing, and asynchronous operation wrappers to support high-performance, concurrent workloads.
