Some thoughts:
* The id attribute for node b is defined, depending on the relations in the
graph, multiple z nodes could be returned for your query.
* You are currently including all relations types, can this be limited?
* Indexes are currently not supported by Apache AGE (see #45). I don't think
your query would benefit a lot from using indices though, since it seems to be
a scalability issue related to the number of relations.
* Running your query with `EXPLAIN` / `EXPLAIN ANALYZE` might provide more
insight in how your query is executed. Please post the results below:
```
SELECT * FROM cypher('graph', $$ EXPLAIN MATCH (z:type1)-[*..4]->(b:type2
{id: 'CI02597329'}) RETURN z.id $$) as (id agtype);
```
```
SELECT * FROM cypher('graph', $$ EXPLAIN ANALYZE MATCH
(z:type1)-[*..4]->(b:type2 {id: 'CI02597329'}) RETURN z.id $$) as (id agtype);
```
* Inversing the query should give the execution path and same performance,
but it is easy to do, so maybe worth trying:
```
SELECT * FROM cypher('graph', $$ MATCH (b:type2 {id:
'CI02597329'})<-[*..4]-(z:type1) RETURN z.id $$) as (id agtype);
```
