New features and notable fixes in Galera replication since last binary release
by Codership (3.22):

• Write set serialization has been changed to use proper memory alignment in order to avoid crashes on platforms which do not allow unaligned memory access (http://www2.galeracluster.com/e/38852/codership-galera-issues-445/88b8yp/875788176)

Notable bug fixes in MySQL 5.7.21: …

“Our three megastores’ and webshop’s combined revenue was 432 million euros in the year 2017. Galera Cluster has been the cornerstone of the system, secured our sales and supported our growth.”

“MySQL master/slave setup was just too fragile and needed regular work to fix each time the slave got out of sync. Now with Galera we’ve found that even if we take a node offline for a while, it re-syncs automatically and without intervention.”

“The big plus is that all nodes have exact the same information, and no node is running for even a fraction of a second behind. This will also mean that no information will be lost!”

“We wanted a solution which was backward compatible with our frameworks, as we have used mainly MySQL, which was reliable and nearly 100% data consistent.  If our application were to execute a commit and receive a successful response, we needed a 100% guarantee that we have rows of data in our database — and for more than that one instance.”

It responded to our needs nearly 100% of the time.”
