Nornicdb is a distributed low-latency, Graph+Vector, Temporal MVCC with all sub-ms HNSW search, graph traversal, and writes. Using Neo4j Bolt/Cypher and qdrant's gRPC means you can switch with no changes while adding intelligent features like schemas, managed embeddings, reranking+llm, GPU accel, Auto-TLP, Policy-based Memory Decay, and MCP server.

High-performance framework for building redis-protocol compatible TCP servers/services

Adaptive hedged requests for Go. Cut your p99 latency with zero configuration. Based on Google's "The Tail at Scale" paper.

Simply ACID* key-value database. At the medium or even low latency it tries to provide greater throughput without losing the ACID properties of the database. The database provides the ability to create record headers at own discretion and use them as transactions. The maximum size of stored data is limited by the size of the computer's RAM.

hypermatch is a high-performance ⚡ Go library designed for rapid matching of a large number of rules to events. It processes thousands of events per second 🚀 against extensive rule sets in-memory with minimal latency ⏱️.
