Благодарю. Я обновил свой вопрос с информацией профиля. Также учтите, что я немного изменил ваш запрос, поскольку исходный запрос не компилируется.
дал динамический конструктор запросов Cypher. Для сложных случаев этот конструктор выдает довольно большие запросы, например:
MATCH (parentD)-[:CONTAINS]->(childD:Decision)-[ru:CREATED_BY]->(u:User)

Сейчас я не очень доволен выступлением. Например, вызов по этому запросу занимает ~ 500 мс
Не могли бы вы взглянуть и сказать, есть ли шанс улучшить этот запрос?
