That is correct.

Hi,
If my HikariCP config has the wrong database credentials, I'd like my server to fail fast.Seems like the only way is to wait for the acquireRetries * acquireRetryDelay milliseconds, then try to call getConnection(), catch the SQLException and then exit.
Do I have that right?
Thanks,

I'll investigate a way to fail the pool fast. Likely it will be via a RuntimeException thrown from the constructor ... but will require that the minimum pool size is non-zero.

If you instantiate your DataSource programmatically, you could use the raw driver DataSource to do the getConnection() check. e.g.:
PGSimpleDataSource dataSource = new PGSimpleDataSource();
dataSource.setUser("username");
dataSource.setPassword("password");
// check raw data source, e.g. dataSource.getConnection();
HikariConfig config = new HikariConfig();
config.setDataSource(dataSource);
HikariDataSource connectionPool = new HikariDataSource(config);
But I guess that won't help if you do this the declarative way.

The recently released HikariCP 1.2.9 has a new property initializationFailFast
that is not yet documented. If you set this to true
, there will be a RuntimeException
thrown when a HikariDataSource
is constructed, providing that the minimumPoolSize
is > 0.
