redis - 如何从 RedisGraph 中删除/删除重复节点

Question

有人可以帮我从 RedisGraph 中删除特定标签的重复节点吗？我在 Neo4j 中找到了密码查询，但在 Redis 中不支持。请帮助我。

我使用了下面的查询，然后 RedisInsight 抛出错误

MATCH (p:Person)
WITH p.id as id , collect(p) AS nodes 
WHERE size(nodes) >  1
RETURN [ n in nodes | n.id ] AS ids, size(nodes)
ORDER BY size(nodes) DESC

错误：RedisGraph 当前不支持列表推导

要删除重复项，您可以使用以下命令

MATCH (p:Person)
WITH p.id as id, collect(p) AS nodes 
WHERE size(nodes) >  1
UNWIND nodes[1..] AS node
DELETE node
