Too few sampled comments (2) to say how often HN recommends it.?
Why HN links it
HN readers link lefred's posts for technical comparisons of MySQL clustering, such as Group Replication versus Galera and how single-primary mode prevents stale reads.
Summarised by Claude from a sample of 2 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
What Hacker News says?
In single primary the other nodes are put in a read-only mode so they can not accept writes. So stale reads can not happen. To expand on your question a little - the MySQL router currently works better for single primary (it supports multi-primary but does not prevent stale reads). If you go third party, ProxySQL also supports Group Replication natively with multi-primary: http://lefred.be/content/mysql-group-replic…

HN discussionVery similar concept, but differences are well described here: http://lefred.be/content/group-replication-vs-galera/ The Tl;dr I give most people is that the Group Replication technology (innodb cluster) uses Paxos for group communication (with majority) and Galera uses Totem Single-ring Ordering (all nodes).
