Frequently asked questions

What is the purpose of `pool.totalCount`?

`pool.totalCount` represents the total number of database connections currently managed by the connection pool.

How does `pool.idleCount` relate to connection pooling?

`pool.idleCount` indicates the number of database connections that are available but not actively being used within the connection pool.

What does `pool.waitingCount` signify in a connection pool?

`pool.waitingCount` represents the number of threads or requests currently waiting for an available database connection from the pool.

How do I obtain a HikariPool instance using dataSource?

You can obtain a HikariPool instance by calling `dataSource.getHikariPoolMXBean()` which provides access to the underlying HikariPool configuration and management.
