Peeyush Bishnoi commented on FALCON-1747:
-----------------------------------------
I thought to add upper bound to numResults value but question is what should be
the upper bound value on numResults for listing the instances status. As users
may pass different value to numResults like 10,50,100 etc. depending on their
use case/purpose and we will not be aware of this all the time.
You have mentioned that the provided fix can introduce OOM, if the calculated
start and end date diff is too much. But without this patch as well, users has
option to provide any start and end date on CLI to get the list of instances
status and with that also start and end date diff can become too much.
Moreover, I have seen that even if specified numResults value is in few
hundreds or less, calculated start date still go much beyond the entity start
date and diff become too much. But we have a check and restrict it to entity
start date only.
So in the provided patch if start date is empty, it is required to calculate
start date in function getStartAndEndDate()/getStartDate() of class
AbstractInstanceManager. If calculated start go beyond entity dates, then we
restrict to entity start date.
