![]() ![]() ![]() Data is read and written directly from/to shared memory, no sockets are used between WhiteDB and the application program. WhiteDB is a lightweight NoSQL database library written in C, operating fully in main memory. The core libraries have a small footprint and install with zero configuration for embedded applications.Ĭayley is an open-source graph inspired by the graph database behind Freebase and Google's Knowledge Graph. It does not require the definition of a database schema, and with the RDF data model model, it can easily add and integrate data of all shapes. Titan is a transactional database that can support thousands of concurrent users executing complex graph traversals in real time.īrightstarDB is an RDF triple store. Titan is a scalable graph database optimized for storing and querying graphs containing hundreds of billions of vertices and edges distributed across a multi-machine cluster. Build high performance applications using a convenient SQL-like query language or JavaScript extensions. To deliver high performance computation and efficiently utilize the high memory bandwidth of GPUs, MapGraph's CUDA kernels use multiple sophisticated strategies, such as vertex-degree-dependent dynamic parallelism granularity and frontier compaction.ĪrangoDB is a distributed free and open-source database with a flexible data model for documents, graphs, and key-values. The API is based on the Gather-Apply-Scatter (GAS) model as used in GraphLab. MapGraph API makes it easy to develop high performance graph analytics on GPUs. HyperGraphDB is a general purpose, open-source data storage mechanism based on a powerful knowledge management formalism known as directed hypergraphs designed mostly for knowledge management, AI and semantic web projects, it can also be used as an embedded object-oriented database for Java projects of all sizes. Through the RAM store, GE enables the fast random data access power over a large distributed data set. The distributed RAM store provides a globally addressable high-performance key-value store over a cluster of machines. Graph Engine (GE) is a distributed, in-memory, large graph processing engine, underpinned by a strongly-typed RAM store and a general computation engine. OrientDB Community Edition 4.Graph Engine Even for a Document based database, the relationships are managed as in Graph Databases with direct connections among records. It can store 220,000 records per second on common hardware. OrientDB is a 2nd Generation Distributed Graph Database with the flexibility of Documents in one product. ![]()
