title: How to Set typeorm connection pool size in Nestjs? (MySQL)
body: <p>I saw this link <a href="https://stackoverflow.com/questions/46843248/create-connection-pool-typeorm">create connection pool TypeOrm</a></p>
  
  <p>This article explained</p>
  
  <pre><code>"extra": {
    "connectionLimit": 5
  }
  </code></pre>
  
  <p>But I thought that this is just max limit of connection instead of creating connection pool in advance</p>
  
  <p>How can I create typeorm(mysql) connection pool in Nestjs?</p>
