We found transactional causal consistency (TCC) anomalies on the Dgraph Cluster. According to link1 (see the following comment), Dgraph provides SNAPSHOT ISOLATION that is stronger than TCC. See the bottom for TCC details. In our experiment we set up the cluster on a local machine with 3 server nod…
