Error found in optimization stage: The depth of plan tree has exceeded the max 512 level

Insert data throw error:
Error found in optimization stage: The depth of plan tree has exceeded the max 512 level

I deployed nebula with https://github.com/vesoft-inc/nebula-docker-compose. How can I change the limit setting?

It's controlled by max_plan_depth, but not sure if it's configurable(else, we have to change it and redo the build of nebulagraph).

@jievince , could we add this as a configuration to be reasonable?

@wey-gu 您好，这个问题我通过分批插入数据解决。目前看来是单次插入数据过多导致。PS：我这里之前是一次插入300条关系数据报错，我改成分三次插入，每次插入100条，现在已经成功。

@terwer 它可能和你的机器配置是有关系的，如果是 HDD 的话，建议每次少量地插入数据。

@terwer 这个 issue 超过一个月没有更新内容了，这边先行关闭了。如果你有任何更新的内容，可以再打开这个 issue 哈。

谢谢你的反馈 😊

update: it's actually already configurable as they are gflags...

This in graphd will help:

--max_plan_depth=2048
