objectgin

ObjectGIN is an open-source graph-based querying and indexation system used for graph databases. Its primary function is to allow for the execution of complex graph queries and maintain efficient indexes for data retrieval. ObjectGIN has been designed to handle large datasets and perform well under heavy loads.

ObjectGIN uses a technique called graph indexing, also known asGamma or NORI, for efficient data retrieval. This technique enables it to quickly find the nodes and relationships that match complex query patterns, thereby improving query performance. It achieves this by structuring data in the form of labeled graphs, which facilitates the efficient verification of relationships between nodes.

ObjectGIN supports a range of data types, including integer, string, and complex object types. It's designed to work with a variety of databases, including PostgreSQL. The project's code is available under an MIT license, allowing customization and adaptation to suit a wide range of use cases.

ObjectGIN's architecture is centered around a primary unit called the "gin" (short for Generalized Inverted Index). The gin primarily holds all the data within ObjectGIN, and this is the unit where all implementations of all indexes reside. New indexes can be implemented easily by subclassing the gin unit.

ObjectGIN is in continuous development, with regular updates and improvements to performance and functionality. It has been adopted in a few industrial-scale projects for query processing and indexing complex data models. However, availability of comprehensive documentation and thorough user support have been raised as potential barriers for adoption by some users.
