Neo4j Graph Platform Cypher
1

Hey, I have a data set with ~1 million nodes and 1 million relations. My goal now is to return all of the data using the neo4j and cypher(QL) but I get a lot of redundancy. My set contains Posts, Authors, Comments and InLinks. The relations are:

  1. Post ->WRITTEN_BY->Author;
  2. Comment ->POSTED_ON->Post;
  3. InLinks ->LINKS->Post.

My cypher is this:
match (p:Posts)-[:WRITTEN_BY]->(author), (c:Comments)-[:POSTED_ON]->(p), (i:InLinks)-[:LINKS]->(p) RETURN p as Post, c as Comment, i as Inlink, author LIMIT 100
and I get an output like:

Post        Comment       InLink       Author
PostID1 CommentID1  InLinkID1  AuthorID1 (for example)
PostID1 CommentID1  InLinkID2  AuthorID1 (for example)
PostID1 CommentID2  InLinkID3  AuthorID1 (for example)
PostID1 CommentID2  InLinkID4  AuthorID1 (for example)
PostID1 CommentID1  InLinkID5  AuthorID1 (for example)

as you can see here, for the same Post and Author but different InLink and Comment I'm getting redundancy aka I'm getting data that is repeating non necessarily. What I'm trying to achieve is

Post        Comment       InLink       Author
PostID1 CommentID1  InLinkID1  AuthorID1 (for example)
                    InLinkID2  AuthorID1 (for example)
                    InLinkID5  AuthorID1 (for example)
-------------------------------------------------------------------------
PostID1 CommentID2  InLinkID3  AuthorID1 (for example)
                    InLinkID2  AuthorID4 (for example)

Any tips on how to do this?
Thank you

you can use WITH statements along with COLLECT.

Thank you, I solved it with

match (p:Posts)-[:WRITTEN_BY]->(author), (c:Comments)-[:POSTED_ON]->(p), (i:InLinks)-[:LINKS]->(p) 
RETURN p as Post, collect(c) as Comments, collect(i) as InLinks, author
