This automatic scaling behavior allows Cloud Functions to handle many requests in parallel, each using a different instance of your function. firebase google-cloud-functions google-cloud-pubsub firebase-admin Version info firebase-functions: "1.0.4" firebase-tools: Not using firebase-admin: "5.12.1" Test case I'm getting ~12 secs of cold start times, and about 50 ms when the function is warm. Not sure what I'm doing wrong and why it would fail only on the first run. I felt my application cold start is slow and was more sure when Firebase Performance mentioned that. It sounds like you're experiencing a so-called cold start of the function. A normal server application is always running so when you call it everything is humming along. A cold start occurs when an AWS Lambda function is invoked after not being used for an extended period of time resulting in increased invocation latency. The cold start-up of the cloud function needs to speed up.

I then moved it to a node.js app, hosted on appengine container.

Just by installing the SDK, you get an automated trace for your app start so you can monitor how long it takes users to go through a cold app start. Then when you hit the function again, it restores the environment from this mode. First Start After Deploy: consistently between 30 and 60 seconds, frequently gives me a "connection error" on the first try when cold (this is after waiting several seconds once Firebase CLI says "Deploy Complete!"

I used logcat Displayed to make an initial compare which displayed at my

可直接行動的分析工具 自訂目標對象（Custom Audiences）：Firebase 讓你可以按裝置、事件 (例如 session_start 或 level_up) 或使用者資源 (例如年齡、性別、語言) 來區隔使用者。在應用上可以推播給特定區隔，廣告上可將專案連結至 AdWords 之後，就可以將目標對象清單匯出到 …

You can import/export JSON to just about any node and can easily turn on daily backups. You’ll also need to initialize your Firebase app with initializeApp(). The other feature Firebase Performance offers is monitoring network activity. For me personally, I'm not experienced in anything there, however, I've just read online it's a problem. The Firebase Admin Java SDK is published to the Maven central repository. 圖片提供：Steven Hsieh 3. ... For example, I would like to receive notifications for the admin … To install the library, declare it as a dependency in your build.gradle file: dependencies { implementation 'com.google.firebase:firebase-admin:6.13.0' }

So Firebase Functions are what you would call “serverless” which is a fancy term for functions as a service.
I insist you give it a shot to try firebase cloud functions and you will wow as I was. Tune in each week and learn how to build realtime apps on Android, iOS, and the Web. npm install --save firebase firebase-queue.

After some research the answer is to do lazy initialization of global variables.

Firecasts is a hands on YouTube series for Firebase developers. Most often it seems to fail the first time it runs after a new firebase deploy and possibly on a "cold start."
