What do you mean by connection pooling?
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.
What’s a connection pool why use it?
Connection pools are used to enhance the performance of executing commands on a database. If all the connections are being used, a new connection is made and is added to the pool. Connection pooling also cuts down on the amount of time a user must wait to establish a connection to the database.
What is connection pooling in spring?
HikariCP is a JDBC DataSource implementation that provides a connection pooling mechanism. If the HikariCP is present on the classpath, the Spring Boot automatically configures it. If the HikariCP is not found on the classpath, Spring Boot looks for the Tomcat JDBC Connection Pool.
How connection pooling is used?
In software engineering, a connection pool is a cache of database connections maintained so that the connections can be reused when future requests to the database are required. Connection pools are used to enhance the performance of executing commands on a database.
Is connection pooling possible with rest?
Statelessness in a REST implementation requires that any state necessary to process a request needs to be included in it. It does not prevent the server to maintain a state anyway for efficiency. A connection pool is ok, so is an authentication cache on the server.
What is object pooling in Java?
In other words, object pooling is nothing but sharing of objects between different clients. Since object pooling allows sharing of objects, the other clients/processes need not re-instantiate the object (which decreases the load time), instead they can use an existing object.
