What is the default connection pool size that spring boot HikariCP provides when the container loads?
of course, I am using below properties to setup max cp size, but I was wondering what is the default CP size if we don't give any number in the application.properties file.
spring.datasource.hikari.minimumIdle=5
spring.datasource.hikari.maximumPoolSize=20
spring.datasource.hikari.idleTimeout=30000
spring.datasource.hikari.poolName=SpringBootJPAHikariCP
spring.datasource.hikari.maxLifetime=2000000
spring.datasource.hikari.connectionTimeout=30000
And if I give a max pool size in application.properties as 100 and I use only 20, will that affect my application performance?
回答1:
maximumPoolSize
Default: 10
HicariCP Documentation contains default properties: https://github.com/brettwooldridge/HikariCP
