Fundamentals
Description A property graph database that stores data as fixed-size records in linked lists for index-free adjacency traversal. Offers community and commercial editions with an extensive graph algorithms library.A PostgreSQL extension that embeds the LadybugDB engine to run Cypher queries from SQL. Registered Postgres tables act as node and relationship labels, and Ladybug's planner rewrites each pattern into a single SQL join executed natively by Postgres; Cypher can also run against Ladybug-native tables stored in the data directory.
