What will happen if my spark plan of cloud firestore exceeds it's limit and I don't upgrade my plan? [closed]

I am using firebase on a free plan (I don’t have billing enabled). As far as I’m aware, free users get 30gb of bandwidth per month. I was wondering if google would cap the bandwidth usage when I reach that limit of if I would continue using bandwidth and end up having to pay for it. Thanks in advance!
Edit: I'm asking about Firestore, not Cloud Storage
If you're on a free plan, if you reach a quota you get cut off, not charged. If you're on the blaze plan (with billing enabled), you get charged for usage over quotas.
However for Firestore, I can't imagine you hitting the bandwidth limit before you hit the read/write limit. Are you sure you're not talking about Firebase Realtime Database? (different product than Firebase Firestore)

I found online that firebase can only handle up to 100 users. Does this mean that after 100 users sign up, you will be forced to switch to a higher plan? That seems like a very low user count.
The limit you're referring to is the limit for the number of concurrently connected users to Firebase Realtime Database on the free Spark plan. Once you upgrade to a payment plan, your project will allow 200,000 simultaneously connected users. This is not the total number of users, just the number of them that are currently running your app. This limit does not apply to other Firebase products (there are over a dozen).
I suggest reading over the pricing page carefully to understand the limits for paid and unpaid projects, for each of the individual Firebase products.
I have upgraded to the firebase Blaze plan since I want to use cloud functions with nodejs 10 and the Pubsub schedule functions but I am a bit scared of overspending by mistake once I reach the free quota.
I am already aware that I can set up some budget alerts to monitor my monthly spending but I am more looking for a safety net solution in case my usage of Firestore suddenly goes through the roof because of an error in the code (infinite loop for example, like it happened to me last week) or even some kind of DDoS attack.
The documentation mentions a daily spending limit which is exactly what I was looking for but it seems to be deprecated since end of 2019. Is there a way to set some kind of quotas for Firestore (read/write per day or minutes) in a similar way to how we can set quotas for the number of invocations of cloud functions?
I find it hard to believe that Gcloud removed the daily spending limit without offering any alternative as it could, in case of human errors, bugs, or even attacks, leave independent developers with gigantic bills they can't afford. I am seriously considering downgrading back to the free plan.
Is there any alternative solution to cap Firestore spending or usage?
It is not possible to set a quota limit on the Firebase operations. This is a known issue but you can mitigate it by setting alerts on the GCP project. There is more information from a Googler in https://stackoverflow.com/a/52325021/6003934
I've just used Firebase & I have 2 questions that hopefully can be answered here.
I was wondering, is the quota for reading 50,000?
And if I exceed that limit, will I have to pay even though I haven't added a credit card or anything to my account.
I want to know this because I don't want to have to pay because I haven't even added a credit card.
If I exceed the quota, will the feature be disabled or will I have to pay?
If you're asking about quotas on the Spark free tier, the daily quota is 50,000 document reads per day, as described in the documentation. If you exceed that quota, queries will fail until the quota is reset the next day.
If you have further question about billing, you should ask Firebase support directly rather than posting to Stack Overflow.
I am a Google blaze plan user and I have an express server containing a simple endpoint that just pulls from firestore. During high traffic hours, I can retrieve 5000+ simultaneous read requests which eventually throws this error below,
Error: 8 RESOURCE_EXHAUSTED: Quota exceeded.
After I wait a few minutes I am able to read the collection again.
Update:
Unsure why the downvotes without any explainations.. but I also have a Mutex system which I think may be leading to hitting these limits. If fails to lock a document using transactions, it goes down an array of snapshots until a lock is given. If the array becomes empty, it does another read to firebase for another set of N documents, which is only 50 in my case.
So my question is, is there a limit on the amount of transactions or reads per second that we're allowed to do from a single connection (my express server)? I don't think it's stated anywhere in the documents.
It looks like you're reaching one of the read/write/transaction limits stated in this page.
Might be this one Maximum writes per second per database: 10,000 (up to 10 MiB per second) but I'm only guessing...
To answer your question, according to this link, the maximum concurrent connections for mobile/web clients per Firebase database is 1,000,000. Thus, your connections seem to not exceed the limits.
For the Blaze Plan project, the limit for Cloud Firestore Document Read is 50K/day, since free usage from Spark Plan is included in Blaze Plan. The limit is such, unless you have set any budget limit in your Billing account. The usage will be reset at midnight of PST. If you upgrade your plan to Flame Plan, the limit is 250K/day.
Here you may read about the official Cloud Firestore Quotas and limits, such as maximum document reads, maximum size for a document, that can be useful. Furthermore you may monitor your database usage and check your plan's limits from the “Usage” tab in the Firebase console. You can check usage over the current billing period, the last 30 days, or the last 24 hours.
Stackdriver Monitoring is also a practical tool for monitoring document reads/writes/deletes, active connections and snapshot listeners.
A good practice, if you want to avoid unexpected charges on your billing account, would be to create an alerting policy based on the Cloud Firestore metrics, as stated here.
Additionally, you can estimate and verify your monthly costs on the “Blaze Plan” by using this Blaze Plan calculator.
For anyone who runs into this issue in the future, please check your App Engine budget settings under "Application Settings". I set the daily spending limit to avoid unnecessary charges during testing and it slipped my mind. I increased the budget and the error is currently gone.
AWS usually sends me an email when my budget has been exceeded.
Everything here https://firebase.google.com/pricing/ that says "/GB" in Blaze plan, if I have less than GB will the price be calculated lower (like Amazon Web Service's) or billed as full GB?
Want to move from AWS but my app has rather small database/storage but requires large amount of access that it exceeded Spark plan. It would be a shame if Firebase bill me full $5 for realtime database that have barely anything. (In that case stick with AWS might be better)
I know this should go to their support but unfortunately this page https://firebase.google.com/support/ told me to come here, and their direct support is capped at 5 times per year..
Prorated. Calculated lower.
Storage charges are prorated on a per-object basis

In the Blaze plan, fees for Firebase Storage are based on usage volume. Firebase Storage usage fees are processed as Google Cloud Storage usage fees.
