Quanlong Huang commented on IMPALA-12901:
-----------------------------------------
[~hemanth619] I think the JIRA description already answers your question. :)
The flag of debug_actions is a global flag which impact all events. So we can't
add the test as e2e tests. With the table property, we can segregate the
impact. Also no needs to restart catalogd.
> Add table property to inject delay in event processing

> We have tests that verify the behaviors during event processing. We use
> global debug action like
> "--debug_actions=catalogd_event_processing_delay:SLEEP@2000" to inject the
> delay.
> It'd be helpful to add a table property for the same which only affects
> processing events on that table. So we can control the delay more
> specifically.
