![]() By default, the environment comes pre-installed with a bunch of libraries. This is where we declare the libraries required to be installed in the cloud function environment to execute our function. This is how the environment knows which function to call to handle a Pub/Sub event.įor the purposes of this article, we will leave the name as is and just update the contents. You can obviously change the main function name, but make sure to update it accordingly in the Entry point function name tab. This is the signature for the main function that gets triggered by a Pub/Sub event. Since we have selected the trigger as Pub/Sub, there should be a single function in this file with the signature hello_pubsub(event, context), populated by default. This file is where all the function code resides and is executed when the trigger event happens. (source: author)Īs you can see, there are 2 files displayed below the Source Code Inline Editor tab. it might not be as sexy as the others, but in my opinion, it's the reliable backbone of everything on the GCP! It’s basically a location to hold any kind of data. Cloud Storage : Well…not much to say here really.In this case, we use it to generate a Pub/Sub event for a topic, every 15 minutes. It can basically schedule anything really. Cloud Scheduler : This is a fully managed enterprise-grade cron job scheduler from GCP.In our case, the Cloud Scheduler will produce a Pub/Sub event which will then trigger our Cloud Function consumer, who is listening for a particular topic from the Pub/Sub service. It enables a system design where there are event producers and consumers, also known as publishers and subscribers. Cloud Pub/Sub : This is an event-driven real-time messaging service that allows us to create systems that communicate asynchronously.It’s a simple task that can be easily adapted to your use case. When it executes, it will run our code that will write the word “money” to a text file and save it in the Google Cloud Storage bucket. This service will be triggered every 15min. Cloud Function: Oh Yes, this serverless compute service will host and execute all our code.We are going to use 4 services from the Google Cloud Platform (GCP) to do this. Hence, this is not recommended for minute precision, complex workflows.Cloud solution architecture. Sometimes (rare circumstances) the scheduled calendar events may be activated with a lead/lag of +-60 minutes. are restrained by your Quotas for Google Services. The number of emails to be sent/day, trigger(s), it's run time etc. Auto email creator after specified responses are collected Create schedules as once, hourly (90 minutes apart), daily, weekly, monthly, yearly with calendar recurrence Stop responses after a specific date and time Stop reponses when maximum number of responses are reached A lawyer or doctor can create appointment bookings by creating an accepting response event in the calendar and setting the daily limit to 20 or variable number of clients. Allow or stop accepting maximum responses for each recurrence eventsĮ.g. Allow or stop accepting responses for recurrence events Ability to schedule variable or fixed number of responses for every event occurances with overall maximum limit Schedule to collect form responses based on google calendar entries Accept during calendar events feature will cease functioning after 7 days Form Scheduler add-on for Google Forms can limit the number of responses and schedule to open or close the form based on the google calendar events.
