Hi, We are using Flink as a timer scheduler and delay in timer execution is a huge problem for us. What we have experienced is that as the number of Timers we register increases the timers start getting delayed (for more than 5 seconds). Can anyone point us in the right direction to figure out what might be happening?
I have been told that `onTimer` and `processElement` are called with a mutually exclusive lock. Could this locking be the reason this is happening? In both the functions there is no IO happening and it should not take 5 seconds. Is it possible that calls to `processElement` starve `onTimer` calls? -- Narendra Joshi
