## Health v2 (maintenance only)
Score: 97/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 99, release rhythm 92, longevity 100
- inputs: {"age_days": 3898, "days_push": 7, "days_rel": 55, "gap_med": 26, "n_releases_24m": 18}
- flags: none
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
TiKV is an open-source, distributed, transactional key-value database written in Rust, using the Raft consensus algorithm and RocksDB for storage. Originally created by PingCAP as the storage layer for TiDB, it is a graduated CNCF project offering both raw and ACID-compliant transactional APIs with horizontal scalability.

## Use cases
- store metadata for object storage services
- build an online feature store for machine learning
- run a petabyte-scale distributed key-value store with ACID transactions
- serve as the storage backend for a MySQL-compatible NewSQL database
- deploy a geo-replicated low-latency key-value database
- store recommendation system data at scale

## When to choose
- you need horizontally scalable key-value storage with strong consistency and transactions
- you want a proven CNCF-graduated storage layer for large-scale online serving
- you need low, stable latency (sub-10ms P99) across 100+ TB of data

## When to avoid
- you only need a simple embedded or single-node key-value store
- you lack the operational capacity to run a multi-node distributed cluster
- you need rich SQL or document features without adding a query layer like TiDB

## Facets
- artifact type: service
- maturity: stable
- function: database
- domain: databases, microservices
- platform: rust, cloud
- tags: key-value, raft, cncf, tidb, rocksdb, geo-replication, horizontal-scaling, distributed-transactions, consensus, linux, docker, kubernetes
