Nested List & Pattern Comprehensions

[stakez]

In the absence of

• Aggregation functions within nested maps
• "All property" map projections

Using Cypher to retrieve data in JSON format is difficult. Using the "WITH" clause outside the map object can force a lack of context that results in compounded queries with huge overhead. It is also near impossible to replicate inline queries similar to "GroupCount" step in gremlin.

That only leaves us with list and pattern comprehensions. While they are helpful, they cannot be nested to return multidimensional array structures from query results. Is there any plan to support a pattern comprehension within a pattern comprehension anytime soon. A sample example (not the exact use case) is shown below.

[(n)-[:FRIEND_OF]->(f:Person) | [(f)-[:FRIEND_OF]->(b:Person) | b.age]]

Any reference from the nested query simply returns null.

Any solution or timeline on this will be appreciated.

I'm sorry but there no specific timeline we can share at this stage.
