We have a 550,000+ row, 5 column, 12 meg "Google Sheets" document we are trying to import and sync into Firebase RTDB.
Firebase says" Read-only and non-real-time mode activated in the data viewer to improve browser performance. Select a key with fewer records to edit or view in real time."
Our backend dev has implemented a code for realtime database sync. But he is saying that due to a Firebase limitation, realtime sync is not working efficiently because of heavy load of the data.
Our dev has tried to sync for (just) 100k entries and it was not working that efficiently over 100k**+** entries.
The spreadsheet use case is for users to search (custom widget for search) one of the column fields and then present another column to the user. This is a key function of the mobile app we hope to launch soon.
What is a good way to reduce the load?

I am currently working on an app which will be used to send important messages as fast as possible to multiple people.
I found out that there is such a thing like firebase with which it is possible to send messages from a custom server to iOS and android devices.
But I need a solid and secure solution and firebase is therefore only my plan b. I would prefer a custom solution.
How can I achieve that a message will be sent to a client without firebase? I do not want the client to check for a new message every x seconds. That would be a waste of data. The triggering must come from the server. Can this be achieved using the observer pattern?
Firebase is a online datebase. If you try to choose a db for your app, you can choose insted MongoDB, which have a online version of db.

I am working on a flutter project with payment integration. I am very good at front end side but when it comes to back-end it hurts. Anyways I want to add this functionality in my app.
The user will pay price for the consultant. Once the transaction is done I want to give the user a option to chat with the support team of the app but for only 2 days not more than 2 days after the payment. I am using purely using firebase for CRUD functions but I am stuck on this. I have done this in php with sessions but I can't figure out how can I do it using firebase.
Any detailed help/guidance will be very helpful.
Thanks.
save user profile inside firestore in a users collection
add a boolean field called subscribed which is an indicator for the user payment, and subscriptionDate
when the user subscribes, record the dattime
every time the user opens your app, first check if he's subscribed or not, then compare the current date with the subscriptionDate
if the user passed the previous step, open the chat page
you can find many tutorials on google that talks about building chat app using firebase in details

I am developing a Flutter app that is using the firebase realtime database. The app shall be used collaboratively by users to collect and analyze data. Users are part of a team and the data that is collected will be associated with the team. For a user to join a team, they are required to use an invitation link that is sent out by the team leader. The invite shall use the teamId which is a unique identifier for each team.
How could I go about this.
It sounds like you have a two-step process:
Create a link for a specific team that the user can click to then get into the app as part of the team.
Sending that link to the user.
For that type of link you can use Firebase Dynamic Links, for which a Flutter wrapper exists: firebase_dynamic_links plugin.
For sending the link you have many options, but the most common ones are to send it through email or SMS/text message. When the user then clicks the link, it can open your app, and you can extract information about the team from the link.
If the target user is already using your app, you can of course skip all this and create a notification system through the Realtime Database. There's nothing pre-made for that, but it's just more use of the APIs you're already using.

So I want to host a personal website that is created on Angular which uses Node.JS and I wanted find a good place to host it.
I was thinking of using Firebase but I don't understand what it means by
100 simultaneous connection (realtime database)
10 GB/month download (realtime database)
10 GB/month bandwidth (cloud firestore)
document writes,reads, and deletes (cloud firestore)
10 GB/month transferred (hosting)
Also, I want to know from the community if this is enough for a personal website? I already have a custom domain.
Firebase Info
It all depends on the amount of traffic to your website, if you're not expecting hundreds of visitors a day then this is definitely enough, that's if your website even uses a database, it means it can accept 100 connections (more simply 100 people) connecting to it at the same time.
In short; this is enough for a personal website.

My App resubscribes whenever there is a connection loss.
I fear this causes a lot of traffic.
Is all data resend on every subscription?
And how can I monitor this traffic?
(I tried Kadira but could not find a traffic amount tab)
To avoid this kind of traffic, you should try iron-router and manage subscriptions for every template/page. This way you subscribe only to data client needs and also in case of reconnect, the usage is no different from refreshing or changing page.
In case you have a one-page app, you should publish only an amount of data user can process at the moment and increase it in case he needs more.
Kadira Debug is really good for monitoring your app, you can monitor query response time, query rate, memory usage etc. Even if that's not exactly what you're looking for, that's for sure a good place to start to see how your app connects with your db.
