每秒写入数据库

Question

我想编写代码，将数据每秒添加到Firebase 10秒。此代码的问题在于，它正在不终止地将新数据立即写入数据库。如何修复setInterval，使其仅在10秒内每秒写入代码？

exports.addWelcomeMessages = functions.firestore.document('messages/{messageId}').onCreate(
  async (snapshot) => {
    const text = snapshot.data().text;
    let timerId = setInterval(() =>
      admin.firestore().collection('messages').add({
        name: 'Firebase Bot',
        profilePicUrl: '/images/firebase-logo.png', // Firebase logo
        text:  text,
        timestamp: admin.firestore.FieldValue.serverTimestamp(),
    }), 1000);
    setTimeout(() => { clearInterval(timerId); alert('stop'); }, 10000);
  console.log('Welcome message written to database.');
});
