DESCRIPTION:
Gizzard is a sharding framework from Twitter for building eventually-consistent distributed datastores. It provides middleware that manages how data is partitioned (sharded) across multiple backend stores, handles replication, routing, and migrations, and ensures system remains resilient under failures and scalable in throughput. Its design emphasizes flexibility of backends (you can use SQL, Lucene, custom stores), supports forwarding tables (mapping key ranges to shards), replication trees, fault tolerance, and idempotence/commutativity requirements for writes to ensure convergence in distributed / partitioned settings. The project is archived.
Caractéristiques
- Flexible sharding / partitioning of data: forwarding tables mapping key ranges to storage shards to distribute load.
- Replication trees: ability to replicate data across multiple backend shards for fault tolerance and availability.
- Support for backend pluggability: various storage backends can be used (SQL databases, Lucene, Redis, etc.)
- Graceful handling of shard migrations (adding machines, rebalancing shards) with minimal disruption.
- Requires write operations to be idempotent and commutative to tolerate failures, out-of-order writes, retries.
- Stateless frontends: Gizzard instances (middleware nodes) are stateless so scaling them is easier; most state resides in shards and configuration.
