FASTER is a high-performance concurrent persistent log and key-value store + cache library in C# and C++, supporting data larger than memory and fast non-blocking checkpointing. The repository is no longer actively maintained; Microsoft recommends its successor Garnet and the Tsavorite storage engine.

Use cases

• embed a fast key-value store in a .NET application
• persist application state larger than memory with fast disk-backed storage
• build a write-heavy cache with point lookups and heavy updates
• add a recoverable commit log with low-latency commits
• implement consistent recovery via non-blocking checkpointing

When to choose

• you need an embedded, in-process key-value store or log in C# or C++
• your workload is point lookups and heavy updates with data exceeding memory
• you want to trade performance for commit latency via checkpointing

When to avoid

• you need a maintained project - use Garnet/Tsavorite instead
• you need a standalone networked cache server rather than an embedded library
• you need C++ support - only the C# version is actively documented
