Managing large application state easily, resiliently, and with high performance is one of the hardest problems in the cloud today. The FASTER project offers two artifacts to help tackle this problem. FASTER Log is a high-performance concurrent persistent recoverable log, iterator, and random reader library in C#. It supports very frequent commit operations at low latency, and can quickly saturate disk bandwidth. It supports both sync and async interfaces, handles disk errors, and supports checksums. FASTER KV is a concurrent key-value store + cache (available in C# and C++) that is designed for point lookups and heavy updates. FASTER supports data larger than memory, by leveraging fast external storage (local or cloud). It also supports consistent recovery using a new checkpointing technique that lets applications trade-off performance for commit latency.
Features
- Latch-free cache-optimized index, in FASTER KV
- A fast persistent recoverable append-only log based on fine-grained epoch protection for concurrency, in FASTER Log
- Architecture as a component that can be embedded in multi-threaded cloud apps
- Asynchronous non-blocking recovery model based on group commit
- A rich extensible storage device abstraction called IDevice, with implementations for local storage, cloud storage, tiered storage, and sharded storage
- A new high performance remote interface, making the store accessible via TCP from remote clients
