I use the dataset generated by LDBC SNB data generator with scale factor 10.
There are kinds of nodes with original id in the raw dataset. I set these original id as
ori_id property as integer type in every node.
In the dataset I generated, there are
7435696 nodes with type
595453 nodes with type
forum. The number of
post nodes is about ten times that of
The following are the pproblems I encountered:
match (n:forum) set n.ori_id = n.ori_id * 2; just took 5427 ms to process.
match (n:post) set n.ori_id = n.ori_id * 2; took 6 hours but still did not finish.
I want to know why the query 2 will need so long time or if it encountered some problems when processing.
