## What it is
Voldemort is a distributed key-value storage system modeled on Amazon's Dynamo, providing automatic replication, partitioning, versioning, and multi-datacenter support. It was primarily developed and used by LinkedIn, which discontinued production usage in 2018 and the project is no longer under development.

## Use cases
- store key-value data across a replicated distributed cluster
- run a Dynamo-style NoSQL database with no single point of failure
- serve batch-computed data from Hadoop at low latency
- replicate data across multiple geographically distant datacenters
- use pluggable serialization like Protocol Buffers or Thrift for rich values

## When to choose
- you need a proven Dynamo-inspired distributed key-value store on the JVM
- you want multi-datacenter replication with versioned data and no central coordinator
- you need to serve Hadoop batch-computed read-only datasets

## When to avoid
- you need an actively maintained project - it is abandoned since LinkedIn stopped using it in 2018
- you need ACID transactions or relational queries
- you want a modern alternative - consider Venice or other maintained NoSQL stores

## Facets
- artifact type: service
- maturity: abandoned
- function: database, caching, serialization
- domain: databases, microservices, big-data
- platform: jvm, self-hosted
- tags: key-value-store, dynamo-clone, nosql, distributed-storage, eventual-consistency, linux
