Hi all, I'm leaning to user neo4j for relation analysis recently. Today I found it took too long for my cypher query took to finish.
I used the batch importer <https://github.com/jexp/batch-import/tree/20> to import all data into neo4j. And I wanted to find the smallest user_id connected (directly or undirectly, path length no limit) to each user_id. Below is the details: neo4j version: 2.1.2 nodes num: 16M (three labels) relation num: 10M cypher query: match (n:user_id)-[:mapping*]-(d:user_id) with n.value as user_id, case when min(d.value) > n.value then n.value else min(d.value) end as people_id return user_id, people_id What should I do to improve my query performance? Any suggestions would be appreciated! Thanks in advance. Guitao -- You received this message because you are subscribed to the Google Groups "Neo4j" group.
