I've been working on a kernel extension https://github.com/ducky427/neo-kafka which pushes all the changes being made to the data in a Neo4j database to a Kafka https://kafka.apache.org/ server. All the changes have a timestamp attached to them. So theoretically it should be possible to play

[Neo4j] Neo4j 2.2M02 and Cypher START clause

2014-12-21 Thread ducky
While testing some code against Neo4j 2.2M02, I realised that cypher queries of type START n=node(1) RETURN n are all breaking with error: Using 'START x = node(1)' is no longer supported. Please instead use 'MATCH x WHERE id(x) = 1' (line 1, column 7) START x = node(1) RETURN x;

OPTIONAL MATCH (a)-[r]-() DELETE a,r RETURN count(*); until it returns 0. You can try higher limits though, depeding on the number of relationships per node, with 10 rels per node this will be 100k ops, with 100 - 1M ops. Michael Am 17.06.2014 um 15:05 schrieb ducky rohit.a
