We are thrilled to announce the release of FalkorDB version 4.0.0-a1, a major update that brings two exciting features to our graph database platform.
Check the new version docker container (we plan to release a cloud sandbox soon)
docker run -it -p 6379:6379 -p 7687:7687 falkordb/falkordb:4.0.0-alpha.1
Notice: the examples bellow are in Java but if Java is not your cup of tea you can find the same examples in other languages here: https://github.com/FalkorDB/demos
Vector Index
The first feature is Vector Index support, which allows you to find nodes using vector similarity search. This means you can store and query high-dimensional vectors, such as embeddings or image features, and find the most similar nodes based on cosine similarity or Euclidean distance. This opens up new possibilities for applications such as recommendation systems, natural language processing, computer vision, and RAG (we’ll extend in future blogs).
package com.falkordb;
import redis.clients.jedis.UnifiedJedis;
import redis.clients.jedis.graph.ResultSet;
import redis.clients.jedis.graph.Record;
public class FalkorDBVectorDemo {
public static void main(String args[]) {
try (UnifiedJedis jedis = new UnifiedJedis("redis://localhost:6379")) {
// Create Vector index on field description in Character
jedis.graphQuery("Books", "CREATE VECTOR INDEX FOR (c:Character) ON (c.description) OPTIONS {dimension:5, similarityFunction:'euclidean'}");
// Fill in the Graph with some data on books and characters
jedis.graphQuery("Books", "CREATE "
+ "(:Character {name:'Bastian Balthazar Bux', description:vecf32([0.1, 0.3, 0.3, 0.4, 0.7])})-[:in]->(book1:Book {name:'The Neverending Story'}), "
+ "(:Character {name:'Atreyu', description:vecf32([0.3, 0.6, 0.2, 0.1, 0.4])})-[:in]->(book1), "
+ "(:Character {name:'Jareth', description:vecf32([0.1, 0.3, 0.1, 0.2, 0.9])})-[:in]->(book2:Book {name:'Labyrinth'}), "
+ "(:Character {name:'Hoggle', description:vecf32([0.3, 0.2, 0.5, 0.7, 0.9])})-[:in]->(book2)");
// Find the book with the character description that is most similar (k=1) to the user's query
ResultSet result = jedis.graphQuery("Books", "CALL db.idx.vector.queryNodes("
+ "'Character', 'description', 1, vecf32([0.1, 0.4, 0.3, 0.2, 0.7])) "
+ "YIELD entity "
+ "MATCH (entity)-[]->(b:Book) "
+ "RETURN b.name AS name");
// Print out the name
for (Record record : result) {
System.out.println(record.getString("name"));
}
}
}
}
Bolt Protocol
The second feature is support for Bolt protocol, which allows seamless transition from Neo4J to FalkorDB. If you are already using Neo4J and want to switch to FalkorDB, you can do so without changing your code or your data model. You can use the same drivers and tools that you are familiar with, and enjoy the benefits of FalkorDB’s scalability, performance, and flexibility.

// Fill in the Graph with some data on books and characters
jedis.graphQuery("Books", "CREATE "
+ "(:Character {name:'Bastian Balthazar Bux', description:vecf32([0.1, 0.3, 0.3, 0.4, 0.7])})-[:in]->(book1:Book {name:'The Neverending Story'}), "

+ "RETURN b.name AS name");
// Print out the name
for (Record record : result) {
System.out.println(record.getString("name"));
}
}
}
