Not sure how to ask so giving an example below.
Data is kept in a database and a retension is applied where older data is ...(deleted, compressed)?
I'm used to application for exchange data for shares, bonds etc.
There data is collected intrasecond for a period and after that period data is transformed to hourly, daily, weekly etc. data by them mean of the price in the period, max of the high, min of the low price etc.
How does this works in AppD? I have seen data is collected during different intervalls so retension seems to be partly part of the data collection but I have not seen documentation on data transforms for retension into other periods. I get the impression retension is merely a delete strategy.
Anyone that can elaborate on this?
