Description
Briefly describe what this PR does :
switchMapcancels the in-flight inner observable as soon as the next timer tick arrives. With interval=1s, if something takes more than 1s (slow query, ...) every tick cancels the previous request before it can emit, so the client never receives data.exhaustMapinstead drops new ticks while a call is still in flightContext / Motivation
