@bmmcq Hi, bingqing wrote some codes for profiling Pegasus, by logging the run time, size of output/communication data of each operator. See if you have any good advice.
Can merge the main branch to see if this has been fixed. @siyuan0322
Can merge main to try again? @siyuan0322
`g.V().out().values("id")` // 属性id, `g.V().out().values("~id")` // 系统生成的global unique id，默认输出为global unique id
@lidongze0629 首先，gremlin也不是返回属性id，而是global unique id，你举的这个例子是刚好global unique id = 属性id了，这个是他modern graph里做了一些hack导致的；其次，只有返回global id才能保证用户拿这个id去查到确定的对象，因为他是全局唯一的，属性id并不能保证全局唯一。可能在这个很小的示例里这个属性id也是unique的，但是稍微大一点就会发现我们可以specify person id = 2，也可以post id = 2, 所以拿这个属性id去查会得到多个点；最后，属性id其实可以很容易通过values("id") 去拿到。

Hey, I am writing a simple converting tool to convert the edge textfile (in the form: src_id\tdst_id) into a binary file. Cheers. https://www.dropbox.com/s/tyh8qcucyhan6tr/convert.cpp?dl=0
Does it mean if I am running on a cluster, I just run 1 thread on each machine, aka `mpirun -npernode 1 toolkits/cc ..` . In addition, is it possible...
I've tested using local `exp_store`. The results are not empty.
您好，感谢使用GIE. 请问，单独执行（不调用subgraph）： `g.V().hasLabel('intopieces').has('commit_time',neq(0)).as('a').out().in().hasLabel('intopieces').as('b').where('a',gt('b')).by('commit_time').outE().limit(10)` 会出问题吗？如果上述有问题的话，能否帮忙试试慢慢精简下gremlin语句，看具体到哪个地方出错。
