I have a use case where:
Data is of the form: Col1, Col2, Col3 and Timestamp.
Now, I just want to get the counts of the rows vs Timestamp Bins.
i.e. for every half hour bucket (even the ones which have no correponding rows), I need the counts of how many rows are there.
Timestamps are spread over a one year period, so I can't divide it into 24 buckets.
I have to bin them at 30 minutes interval.
