Maja Kabiljo commented on GIRAPH-861:
-------------------------------------
Which race condition are you referring to? Adding this barrier can slow down
some applications which use both inputs (for example if you have just a few
input splits currently other workers will start loading edges while these few
load vertices - this way they'll all have to wait doing nothing - I was even
thinking about improving this so that we can have vertex and edge input threads
at the same time so we wouldn't waste anything).
> Vertex/Edge loading should be distinctive phases
