如何设置光滑的threadPool大小？

这是我的配置：

pp {
  profile = "slick.jdbc.OracleProfile$"
  db {
    url                 = "jdbc:oracle:thin:@52.4.90.244:1521:pp"
    driver              = oracle.jdbc.OracleDriver
    keepAliveConnection = true
    connectionPool      = disabled
    user                = "xxx"
    password            = "xxx"
  }
}

实际上我只在流中执行一个查询，我真的需要一个threadPool吗？我的目标只是从表中检索所有行。

到目前为止，我遇到以下错误：

*** (s.basic.BasicBackend.stream) Signaling onSubscribe(slick.jdbc.JdbcBackend$JdbcStreamingActionContext@76f2bbc1)
*** (s.basic.BasicBackend.action) #1: [fused] cleanUp
      try: andThen
        1: PushStatementParameters StatementParameters(ForwardOnly,ReadOnly,null,null,100)
        2: StreamingResultAction [select * FROM DRUG]

如何在Slick中设置ThreadPool大小？
