firebase cloud function run after 10 seconds

Question

I have a function similar to the one below. triggered when a user submits an application. looking for a suitable match with another user. If it doesn't find a match, I want it to check again after 10 seconds. I want it to call the function "deleteReference(gameid)". this function will also check again. the reference will be deleted if no other user has matched with it.

In some questions, they talk about a solution with a delay, but they are paid for the time they wait. How can I trigger the function I want after 10 seconds (by sending the gameID variable)? with the most affordable cost.

exports.myFunction = functions.database.ref('/match/{gameid}/').onCreate((snapshot, context) => {

    //do some processing here
    
    if (matchResult == true) {
        return null;
    } else {
        // HOW CAN I CALL THIS FUNCTION AFTER 10 SEC ?
        deleteReference(gameid)
        return null;
    }
});

function deleteReference(gameid) {
    //do some processing here

    if (matchResult == false) {
        database.ref("/match/").child(gameid).remove();
    }
}

One option is by using Cloud Task as linked by @samthecodingman. You could also use setTimeout() to delay the execution of the deleteReference() function. See sample code below:

exports.myFunction = functions.database.ref('/match/{gameid}/').onCreate((snapshot, context) => {

    //do some processing here
    
    if (matchResult == true) {
        return null;
    } else {
        // Execute the function after 10 seconds
        setTimeout(deleteReference(gameid), 10000)
        return null;
    }
});

function deleteReference(gameid) {
    //do some processing here

    if (matchResult == false) {
        database.ref("/match/").child(gameid).remove();
    }
}

exports.example = functions..({
setTimeout(() => {
//Your code
}, "milliseconds here");
});

Remember that Stack Overflow isn't just intended to solve the immediate problem, but also to help future readers find solutions to similar problems, which requires understanding the underlying code. This is especially important for members of our community who are beginners, and not familiar with the syntax. Given that, **can you [edit] your answer to include an explanation of what you're doing** and why you believe it is the best approach? – Jeremy Caney May 07 '23 at 01:23
