I have noticed if I write queries with complex usage of the 'with' clause, I get the warning shown below discussing the 'eager' operator. Can someone tell me what this is, where can I find more info on it in the manuals, and what I can do in the sample query to eliminate the warning?
LOAD CSV WITH HEADERS
FROM 'file:///xxx.csv' as rowStore
with rowStore.Entity as Entity, rowStore.EventType as EventType, date(rowStore.Timestamp) as EventDate
on create set r.EventDate = EventDate
on match set r.EventDate = apoc.coll.min([r.EventDate, EventDate])
with n, EventDate
where r.EventDate <> apoc.coll.min([r.EventDate, EventDate])
