We have been using dgraph v1.2.5 and everything was working fine. But when we upgraded to v1.2.6 schema building started taking too much time. We are seeing lots of following messages in logs:
Wondering if you can try Dgraph v1.2.7 - it’s the latest release of the 1.2.x series. Speaking of which, 1.2.x will come to end of life in January. Perhaps you should upgrade to something newer?
