Firebase Cloud Function: Generate snapshot after specified interval

I am writing a cloud function that triggers the onWrite event in the real-time database. However, I want to hold the execution of the function for a few seconds and then check the values of a few variables. However, the snapshot that I would receive would be at the instant the function starts to run right? Is there any way I can ask the system to wait once it's triggered, and then after 3 seconds(say) get the data values from my database and process them as required? Or is there anyway I can regenerate a fresh snapshot after 3 seconds and use it?

The snapshot that is passed into your function contains the value as it existed when the function was triggered.

If you want to get the current value after a few seconds, you can load it:

snapshot.ref.once("value").then((newSnapshot) => {
  ... in here you can check newSnapshot.val()
})
