We’ve been covering papers from VLDB 2019 for the last three weeks, and next week it will be time to mix things up again. I really do want to cover this one at some point, along with Implementation of cluster-wide logical clock and causal consistency in MongoDB from SIGMOD 2019. What’s their secret??? Do we want that? Yes please!
