Hi,
I am trying to join two tables say, T1 and T2. Table T1 has around 8 million records and T2 has 20k records. Table T1 has two fields enterance_date and exit_date and T2 has field movement_time. All the fields are in DateTime format.
I need to perform join on the two tables for the below condition,
[entrance_date] <= [movement time] && [exit_date] >= [movement time]
I tried using the Advance Join macro from analytics gallery to join for above condition and it looks like below:
The condition has been put as shown below:
When i ran the flow, it turned out that the join was behaving extremely slow(possibly because of cross join of huge no of records) and was taking hours to get completed.
Is there a way to improve the performance, for the above problem?
Thanks
