What it does

FalkorDB provides a super fast graph database for your startup, utilizing GraphBLAS for sparse adjacency matrix graph representation to power Knowledge Graphs for Large Language Models (LLMs)

When to use it
  • •Building a knowledge graph for an LLM
  • •Needing a high-performance graph database for complex relationships
  • •Developing applications requiring fast graph queries and traversals
Ready-to-paste prompt
Run `./falkordb_client -h localhost -p 8000 -q 'MATCH (n) RETURN n'` to query all nodes in the graph
Heads up: Ensure you have CMake and a C compiler (such as GCC) installed on your system, as FalkorDB is built using C and requires these tools for compilation
