This article explained这篇文章解释了
"extra": {

How can I create typeorm(mysql) connection pool in Nestjs?如何在 Nestjs 中创建 typeorm(mysql) 连接池?
From the words of one of the authors:用其中一位作者的话来说:
TypeORM creates a connection pool and uses connection for a single operation (find, save, remove, etc.) - it takes the connection, uses it and releases it.
TypeORM 创建一个连接池并将连接用于单个操作(查找、保存、删除等) - 它获取连接、使用它并释放它。 That's it.
而已。 If all connections are busy it waits until any of them is released and then use it.
如果所有连接都忙,它会等待它们中的任何一个被释放然后使用它。
If you want your pool to have a max size, then extra.connectionLimit
is the way to go.如果您希望您的池具有最大大小,那么
extra.connectionLimit
是通往 go 的方式。
