KV Database using Object Storage

Netsy is a durable, replicated key-value database which stores data in object storage.

A drop-in etcd replacement for Kubernetes, or a general-purpose KV store — with durable, low-latency persistence and no operational complexity.

Implements Range, Txn, and Watch — supporting all options used by Kubernetes. A drop-in replacement.

Data is durably stored in object storage via snapshots and chunked deltas. No local disks to manage.

Quorum-based replication inspired by PostgreSQL, with automatic leader election.

Built-in leader election via s3lect with graceful failover and automatic recovery from node failures.

Start a fresh node and Netsy automatically restores from object storage snapshots and chunks.

Coordinated compaction can remove historical revision data across all nodes to reclaim storage.
