I have a client who has invested significant amount time and money in Firebase Realtime Database. Now with this move, I am not sure if Google will support Firebase Realtime Database for next 5 years. So a full rewrite might be needed.
Once more it seems that going Cloud Native on one of Google's proprietary tools is very risky. I know many of the readers will say that Firebase Real-time Database is still supported. But the main question is: will it stay supported for years to come?
Google please please make an announcement and make a commitment to keep Firebase Realtime Database alive for "X" years to come. Otherwise, you are just making us developers lose faith in you.
