title: How to restrict initial pool size in hikaricp?
body: <p>I used to have a <code>tomcat</code> connection pool configuration restricting the initial pool size: <code>spring.datasource.tomcat.initial-size=2</code></p>
  
  <p>Now switching to <code>hikaricp</code>: what is the equivalent to restrict the initially started connections?</p>
  
  <p>Sidenote: <code>spring.datasource.hikari.minimumIdle</code> does not prevent initializing 10 connections at startup.</p>
