Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Gizzard is an open source sharding framework to create custom fault-tolerant, distributed databases. It was initially used by Twitter and emerged out of a wide variety of data storage problems. Gizzard operates as a middleware networking service that runs on the Java Virtual Machine. It manages partitioning data across arbitrary backend datastores, that allows it to be accessed efficiently. The partitioning rules are stored in a forwarding table that maps key ranges to partitions. Each partition manages its own replication through a declarative replication tree.
