Why are we using C3P0 as the default pool?

[zaman.i...@gmail.com]

Is there some specific reason, shouldn't we be using HikariCP or any other better alternative?

[bill robertson]

Is there a way to change that?

[zaman.i...@gmail.com]

You can by overriding the provider_class property available in the configuration. You can read about it here - https://vertx.io/docs/vertx-jdbc-client/java/


provider_class

The class name of the class actually used to manage the database connections. By default this isio.vertx.ext.jdbc.spi.impl.C3P0DataSourceProvider but if you want to use a different provider you can override this property and provide your implementation.

Thanks. 

Are there known issues with vert and HikariCP?

There are no known issues with Hikari, or BoneCP or Agroal (the current alternatives) however the configuration is different and since we were using json it is not trivial to spot this.

An desired improvement is to have a data object that would unify / validate per pool.
