Gizzard is a Scala sharding framework from Twitter for building custom, eventually-consistent distributed datastores. It acts as middleware that partitions data across arbitrary backend stores (e.g., SQL databases, Lucene) using forwarding tables and declarative replication trees.

Use cases

• shard data across multiple backend databases
• build a custom distributed datastore
• replicate data across machines with fault tolerance
• partition large datasets that don't fit on one machine
• manage key-range-based routing to database partitions

When to choose

• you need a flexible sharding layer over arbitrary backends on the JVM
• you want to build a custom eventually-consistent datastore rather than adopt a full distributed database

When to avoid

• you need a maintained project - it is archived and unsupported by Twitter
• you want a turnkey distributed database rather than a framework to build one
• your stack is not JVM/Scala
