Pavel Tupitsyn updated IGNITE-24659:
------------------------------------
Description:
See attached example. When we perform a table update in a compute job or in a
streamer receiver, and the job gets executed on another node (client ->
node1[handle request] -> node2[execute job]), we don't send correct
observableTimestamp back to the client. As a result, the client does not
observe the changes in the table immediately. If you uncomment Thread.sleep in
the example, the code works as expected.
This bug might be fixed by IGNITE-23806. If we don't find a good solution or
don't have enough time, the fix is to always return
*clockService.currentLong()* (important: use *current()* instead of *now()*)
from the node that executes the job/receiver.
