EndKV

EndKV is an open-source distributed key-value storage system designed to provide scalable, low-latency access to large data volumes. It offers a simple API for storing and retrieving binary data by key and is intended to run across clusters ranging from a few nodes to thousands.

The project emphasizes a modular architecture. It employs shard-based data partitioning and replicates data across multiple nodes to tolerate failures. EndKV supports configurable consistency levels, enabling both fast, low-latency reads and writes as well as stronger guarantees when required. The API layer is separated from the storage engine, and the system provides pluggable backends for persistent storage and transport. Client libraries are available for several programming languages.

Key features include horizontal scalability, high availability, and support for multi-region deployments. EndKV offers atomic batch operations, options for encryption of data in transit and at rest, and tools for operational tasks such as monitoring, backup, and rolling upgrades. The design prioritizes simplicity, good documentation, and a manageable operational footprint to suit both development and production environments.

EndKV originated as an open-source project developed by a community of contributors. It is distributed under an open-source license and has seen adoption by organizations and researchers exploring large-scale key-value workloads. The project maintains a public repository with issue tracking, releases, and governance discussions, inviting participation from users and developers alike.
