alt Hacker NewsTo me the biggest "unknown" with Percona is that MariaDB (the company) bought out Codership (the creators of Galera Cluster, which XtraDB Cluster is based on) and it doesn't seem to be OSS any more.
I'm sure for some shops this will drive them to pay for the same feature in MariaDB cluster, but I'm more likely to just transition to MySQL Group Replication.
This is my whole point about MariaDB - they are steadily making their OSS software completely dependent on the company (paid) versions for anything beyond toy scale.
I don't think your last sentence is fair. Many workloads don't need something like Galera, as standard async replication scales to extreme levels, and you can achieve excellent HA with external orchestration and/or proxies. FOSS MariaDB is definitely not toy-scale only.
Oracle has also been guilty of locking modern table stakes behind the MySQL Enterprise / Heatwave pay gate, such as vector indexes and JS stored procedures. And while they've recently announced more of this stuff will move to FOSS soon, at the same time their response rate to new bug reports has become worse than ever before, which is deeply worrying.
And a couple days ago Oracle announced that they're nonsensically changing their MySQL versioning/LTS naming yet again. So now the way you identify an LTS is "major version is an even-numbered last two digits of a year, while minor version is exactly 4 to represent LTS releases always being in April." So for example MySQL 28.4 will be LTS, but 28.7 and 28.10 are not. But prior to this, 9.7 and 8.4 are LTS, and 8.0 was de facto LTS but now EOL. It's bizarre. I wish I was joking!
