“Cold start” in Google Cloud Functions refers to the delay that occurs when a function is invoked after being idle. This can be mitigated by several strategies:
1. Keep functions warm: Regularly ping your function every few minutes to prevent it from going idle.
2. Minimize dependencies: Reducing the number of external libraries and SDKs used in your function can decrease cold start time.
3. Use connection pooling: Reuse database connections instead of creating new ones each time a function is invoked.
4. Opt for higher memory: Higher-memory functions tend to have faster startup times.
5. Bundle your code: Instead of loading multiple JavaScript files, bundle them into one file using tools like Webpack.
