@sucheta- can you verify that running label propagation identified several distinct communities or reasonable size (and not just that you end with many communities with few nodes in each)? For example, if you run
MATCH (n:connparams)
WITH COLLECT(id(n)) AS community, n.partition AS partition
RETURN partition, SIZE(community) AS num ORDER BY num DESC LIMIT 25
this will show you the size of the 25 largest communities.
