H-Store is an experimental database management system (DBMS) designed for online transaction processing applications developed by a team at Brown University, Carnegie Mellon University, the Massachusetts Institute of Technology, and Yale University.[1][2] The system's design was developed in 2007 by database researchers Michael Stonebraker, Sam Madden, Andy Pavlo and Daniel Abadi.[3][4][5]

Architecture

H-Store was promoted as a new class of parallel database management systems, called NewSQL,[6]that provide the high-throughput and high-availability of NoSQL systems, but without giving up the transactional guarantees of a traditional DBMS known as the ACID properties.[7] Such systems use a computer cluster on multiple machines, as opposed to moving to a more powerful, more expensive machine for a single-node system for more performance.[8]

H-Store is able to execute transaction processing with high throughput by forgoing much of legacy architecture of System R-like systems. For example, H-Store was designed as a parallel, row-storage relational DBMS that runs on a cluster of shared-nothing, main memory executor nodes.[9] The database is partitioned into disjoint subsets that are assigned to a single-threaded execution engine assigned to one and only one core on a node. Each engine has exclusive access to all of the data at its partition. Because it is single-threaded, only one transaction at a time is able to access the data stored at its partition. Thus, there are no physical locks or latches in the system, and no transaction will stall waiting for another transaction once it is started.[10]

Licensing

H-Store was licensed under the BSD license and GPL licenses. By 2009, the VoltDB company developed a commercial version, and the H-Store research group shut down in 2016.[11]
