hyperdex |
HyperDex is an open source distributed data store. In the NoSQL data store space, HyperDex distinguishes itself by offering high performance, a rich API, ACID transactions that span multiple objects, and strong consistency and fault-tolerance guarantees. It was developed by a systems team at Cornell University through a multi-year research project.
Main features
- Distributed
- Data is distributed across the cluster, without a single point of failure.
- Flexible Data Model
- HyperDex can act both as a key-value datastore and a document store, supporting unstructured (schema-free), semi-structured, and structured (schema-based) data.
- High-Performance
- Next-generation replication and query protocols enable HyperDex to process operations with minimal overhead.
- Scalability
- Read and write throughput both increase linearly as new machines are added, with no downtime or interruption to applications.
- Fault-tolerant
- Data is automatically replicated across multiple servers to tolerate a user-specified number of concurrent failures. Failed nodes can be replaced with no downtime.
- Strong consistency
- HyperDex guarantees that every GET returns the result of the latest PUT. There are no complicated consistency models to learn or programming quirks, such as conflict resolution, to master.
- Multikey transactions
- HyperDex supports ACID transactions that span any number of objects.
Performance
A performance test that measures performance of HyperDex using identical setup to an independent study that evaluates the performance of Apache Cassandra, MongoDB, and HBase side-by-side shows HyperDex to have superior throughput and latency.[1][2] Multi-dimensional hashing is achieved through a different mechanism called hyperspace hashing than BigTable's multiple column approach. The consistency guarantee is achieved through a novel chaining protocol.[3]
Supported languages
HyperDex supports C, C++, Go, Java, Node.js, Python, Ruby.
