The record

Purpose: Garnet is a remote cache-store from Microsoft Research designed for high performance, extensibility, and low latency.
Protocol and clients: Garnet uses the RESP protocol and works with many unmodified Redis clients, including StackExchange.Redis.
Data APIs: Its API includes strings, lists, hashes, sets, sorted sets, geo operations, HyperLogLog, bitmaps, ACLs, pub/sub, transactions, and Lua scripting.
Storage and recovery: Garnet supports datasets larger than memory using local or cloud storage, along with checkpointing and recovery.
Cluster features: Multi-node cluster mode supports sharding, state migration, and replication.
Extensibility: A custom operator framework lets developers register C# data structures and read-modify-write operations.
Preview features: Vector database support using DiskANN and range index support using Bf-Tree are marked preview.
Platforms: The server is extensively tested on Windows and Linux, and is also described as running on Azure hardware and edge devices.
Security: Garnet supports TLS/SSL connections and RESP password-based authentication.
Compatibility limit: Garnet is not intended to be a fully compatible Redis drop-in replacement, and it does not support Redis modules.
Managed service: Azure Cosmos DB Garnet Cache handles infrastructure provisioning, scaling, patching, and monitoring automatically; it is in expanded Private Preview.
Integrations: The documented Redis client libraries include StackExchange.Redis, Jedis, Redisson, redis-py, node_redis, and go-redis.
License: The Garnet project is licensed under the MIT License.
Support and community: The project site links to Discord and GitHub for community and project information.
