Node.js
A service reads from a fast database cursor and writes each row to a slow external API, using raw writable.write() calls in a loop with no backpressure handling. What's the most likely symptom under sustained load?
A
No issues, since Node handles this automatically
B
Growing memory usage as the internal write buffer accumulates unconsumed data faster than the slow API can drain it
C
The database cursor will throw an error
D
The external API calls will automatically batch themselves
