What is connection pooling?
Connection pooling is a technique of creating and managing a pool of connections that are ready for use by any thread that needs them. Connection pooling can greatly increase the performance of your Java application, while reducing overall resource usage.
What is connection pool in datasource?
Connection pooling means that connections are reused rather than created each time a connection is requested. To facilitate connection reuse, a memory cache of database connections, called a connection pool, is maintained by a connection pooling module as a layer on top of any standard JDBC driver product.

A connection pool is created for each unique connection string. When a pool is created, multiple connection objects are created and added to the pool so that the minimum pool size requirement is satisfied.

What is connection pool settings?

Configuration is necessary only if you want to customize how pooling is done, such as to control the size of the pools and which types of connections are pooled. You configure connection pooling by using a number of system properties at program startup time.
How do I know if my connection pool is working?
A simple way to check pool members are re-used: If your JDBC vendor is using the standard toString from Object you should see the same values printed when you print the connection: System. out. println(“Connection=”+conn);
What is connection pool in SQL?
Why do we need database connection pool?
Database connection pooling is a way to reduce the cost of opening and closing connections by maintaining a “pool” of open connections that can be passed from database operation to database operation as needed.
