RedisGraph GraphBLAS Enabled Graph Database
See publicationRedisGraph is a Redis module developed by Redis Labs to add graph database functionality to the Redis database. RedisGraph represents connected data as adjacency matrices. By representing the data as sparse matrices and employing the power of GraphBLAS (a highly optimized library for sparse matrix operations), RedisGraph delivers a fast and efficient way to store, manage and process graphs. Initial benchmarks indicate that RedisGraph is significantly faster than comparable graph databases.

Methods, systems, and media for resolving database queries using algebraic expressions using matrix-matrix multiplication
Issued US10621235B1
See patentMechanisms are provided for resolving database queries. These mechanisms identify a connected component in a query graph corresponding to a database query. They then determine a longest path length for the connected component. Next, the mechanisms select a path having the longest path length and build an algebraic expression for the path. Finally, the mechanisms solve the algebraic expression using matrix-matrix multiplication to provide a solution, and then respond to the query based on the…
