c3p0 is a Java library that provides a convenient way for managing database connections. In short, it achieves this by creating a pool of connections. It also effectively handles the cleanup of Statements and ResultSets after use.
The Hibernate Connection Pool Size property establishes the number of connections that are permitted between the Model repository and the Model Repository Service database. The default value is 10. In deployments with many concurrent connections, you can increase the property to increase performance.
A connection pool maintains a specific number of open database connections to an application in the main memory. The default size of the database connection pool is eight, but you can change this number while deploying or updating an application in the SAP BTP cockpit.
The connection pool configuration settings are: Initial and Minimum Pool Size: Minimum and initial number of connections maintained in the pool (default is 8) Maximum Pool Size: Maximum number of connections that can be created to satisfy client requests (default is 32)
The InitialPoolSize is 3 by default.
