Как установить триггер для изменения даты всех связанных узлов в neo4j?

Как установить триггер таким образом, чтобы при изменении даты родительского узла автоматически изменялась дата окончания и даты начала связанных с ним узлов?Мой триггер выглядит примерно так: 

CALL apoc.trigger.add(
'update_date',
'UNWIND apoc.trigger.propertiesByKey({assignedNodeProperties},"start_date") as prop
WITH prop.node as n 
match (n)-[:precedes_fs]->(m)
SET n.end_date = apoc.date.toISO8601(apoc.date.add(apoc.date.fromISO8601(n.start_date), 'ms', n.duration, 'd'), "ms")
, m.start_date = apoc.date.toISO8601(apoc.date.add(apoc.date.fromISO8601(n.end_date), 'ms', 1, 'd'), "ms")', {phase:'after'});

, но мой запрос - 

match(n) where n.wbs="1.3" set n.start_date="2019-03-19T11:30:00.000Z"

выполняется слишком долго (никакого результата вообще - запрос продолжает вращаться в браузере neo4j и ничегов журнале отладки).Я использую Neo4j Enterprise версии 3.5.4 - Любые предложения приветствуются

Правка - Свойства моего узла выглядят примерно так - (все они имеют одну задачу метки)
