Constants

const (
	// If a tablet's hostname ever goes over 60 chars then it will not be able
	// to boostrap properly because it will truncate the master hostname and replication will fail.
	// See the chart at the bottom of https://dev.mysql.com/doc/refman/8.0/en/change-master-to.html
	MaxTabletHostnameLength = 60

	// allow up to 99 replicas. Statefulsets can go higher, but it's not likely for this use case
