I'm building a Firebase app, and plan to use the real-time database when I need real-time updates. However, most of the application data is more traditional.
Now that Functions is a thing, how do I also leverage either DataStore or CloudSQL? Can anyone point me to specific documentation or examples how to read/write with either of those services from a function?
Neither Cloud Datastore nor Cloud SQL support Cloud Functions yet, which means you aren't yet able to trigger Cloud Functions based on their events the way you can with the Firebase Realtime Database.
Fortunately, once a Cloud Function has been triggered (for example via HTTP), you can still read and write from Datastore and SQL as you would from any other Node.js code. Here is documentation for Cloud Datastore, and here it is for Cloud SQL.
Finally, if you're adventurous and might like to provide early feedback on upcoming integrations like Datastore, fill out this form!

Is there any way to check how many read/write on my app on Cloud Firestore?
There currently is no API to get the number of reads/writes from Cloud Firestore. Neither the client-side SDKs nor the server-side Admin SDKs expose this functionality.
The closest I can think of is something based on StackDriver monitoring that you can set up for Firestore. Based on that you can then wrap the StackDriver monitoring API in a custom end point (either in Cloud Functions or elsewhere).
I was looking at a few ways to export data out from Firestore without using export (expensive operation in the long term as it doesn't support incremental backups) to use in BigQuery and Data Studio.
1) Using Google Pub/Sub.
This will probably require function to both write to pub/sub and then another to trigger to BQ.
2) Using Cloud Functions to trigger from an onCreate event to write directly to a BigQuery dataset and table.
(This is using table.insert)
What would the advantage be to use Pub/Sub - other than it would appear that it will cost more in the long term?
Or is there another way I am unaware of to do this?
I'm new at this. Some advise and pro and cons of the above scenarios are much appreciated.
The official solution is here.
In case of using Cloud Functions to trigger from an onCreate event, what will you create? Create File on Cloud Storage or create Firestore Document?
I think that in case of using Cloud Functions you should use PubSub trigger.
I recommend asynchronous architecture like Pub/Sub. Because rerun is easy and the scope of influence is limited.
I developed sample is here. I'm using Cloud Scheduler not cron.yaml. The cost of Cloud Scheduler is here.
(If you want) Export Firebase Authentication users to Cloud Firestore Collection. Use Firestore, Cloud Functions(PubSub) and Cloud Scheduler.
Export All Cloud Firestore Collections and Specified collections to Cloud Storage. Use AppEngine and Cloud Scheduler.
Export Specified Cloud Firestore Collections to BigQuery( as Partitioned tables). Use AppEngine and Cloud Scheduler.
I'd like to implement a full text search an app that is using Cloud Firestore.
Integrating with Algolia sounds great, but it can't work on the free Spark plan since outbound networking is limited to Google services only.
Therefore, the obvious question:
(1) Is it possible to use firebase-functions to create a function that monitors Firestore changes and deploy it to something like Zeit's Lambda or AWS Lambda?
Somewhat related question:
(2) Is it possible to use onSnapshot instead of onCreate/onUpdate/etc. to monitor Firestore changes?
You can't deploy Cloud Functions code to other serverless function providers. You can certainly try to reuse your core logic, but each provider has its own APIs and infrastructure, and firebase-functions only knows how to work with Cloud Functions.
I want to read and write data in database real time across cloud functions but I don't know if this is possible, also I don't know if this is good practice or if is better make this through with SDK database realtime
I learning firebase and react native, I am new learning these topics.
From the docs:
Cloud Functions for Firebase lets you automatically run backend code in response to events triggered by Firebase features and HTTPS requests. Your code is stored in Google's cloud and runs in a managed environment. There's no need to manage and scale your own servers.
Cloud Functions runs Node v.6.11.5, so we recommend that you develop locally with this version.
You are able to use realtime database trigggers like onCreate(), onWrite(). Also you are able to use set() to send data to the realtime database.

As I know currently Cloud Functions doesn't support triggering functions from Firebase.
For now I'm planing to use an basic Engine instance to trigger the functions based on the queue.
Is this the right way to go? or should I trigger the cloud function directly from the clients device after the data is inserted in the db?
thank you
Cloud Functions for Firebase was just launched today! You can use the SDK to trigger cloud functions from your Firebase database, storage bucket, authentication, and analytics events. https://firebase.google.com/docs/functions/
