XtraDB Cluster Member


Is the ideal number of members in database configuration three? Will there be conflicts when there are 5 or more?


Hello @Akif_Sinmaz,
3 or 5 is ideal. You don’t want an even number because that can lead to split-brain issues. There won’t be any more conflicts with 5 nodes vs 3 nodes. As always, the best-practice and recommendation is to only write to one node. The other nodes are there for HA and read-only traffic.
