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.
