redis - 如何从RedisGraph删除/删除重复节点

Question

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

我用下面的查询，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当前不支持列表理解

要删除重复项，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
