Why 'Quarkus' chose 'Agroal' instead of 'HikariCP' as the preferred datasource and connection pooling implementation?

Question

In Quarkus, the preferred datasource and connection pooling implementation is Agroal.

But, I don't see any review or comparison of 'Agroal' with the well known JDBC Connection Pooling implementation 'HikariCP'.

What makes 'Agroal' better than 'HikariCP', except that BOTH Quarkus and Agroal are from RedHat?

With Agroal you can update configuration on runtime

Configuration property overridable at runtime

While Hikari doesn't support it

You can't dynamically update the property values by resetting them on the config object

features first class integration with the other components in Quarkus, such as security, transaction management components, health metrics

Well, I would want to buy this argument that there is SOMETHING DIFFERENT, but, one probably wants to have a better performing Connection Pool instead of a dynamically configurable connection pool. I would choose this as an accepted answer, if I don't get anything with regard to 'performance' bench mark! – RafiAlhamd Feb 09 '20 at 14:47
On the other hand, I too see an alternate work around to achieve dynamic configuration in HikariCP in this [answer](https://stackoverflow.com/a/49904258/7678737). So, I'm still wondering what made 'Agroal' as the choice. – RafiAlhamd Feb 09 '20 at 14:50
@RafiAlhamd Another reason is Quarkus integration (see update) – Ori Marko Feb 09 '20 at 14:58
Looking at the number of [libraries supported by Quarkus](https://code.quarkus.io/), definitely, HikariCP could have been included. But, why _HikariCP_ was *avoided / ignored* is the curious question! – RafiAlhamd Feb 09 '20 at 15:09
Moderators have closed this question. No choice for now. But, need to find a way to get answer! – RafiAlhamd Feb 09 '20 at 16:40

Happened to get answer from Quarkus Co-founder _Emmanuel Bernardin_ in Twitter. His answer: "Agroal is like Hikari in perf but with additional features around XA and security that we needed for Wildfly and Quarkus.".
