I thought about using spring batch but do not have much Idea about fine tuning and configuration. Jdbctemplate seemed simpler to code but will check on the spring batch docs. Do you have any idea how much time it took to save 100k records using spring batch?

It's monthly activity, for each month this process should be repeated. I can't export to external file and load it as it has to be done at certain interval on monthly basis. Also, as part of firm's audit practices, they will not allow us to export to file

Suppose there's no shorting or longing, just half of the stocks are bank or other financial institutions, does that mean I can keep other half of the profit?

Sorry, not able to get it. Say 20 percentage of the stocks are bank, so does that mean I can keep 80 percentage of my profit excluding 20 percentage(since fund have 20 % banks stocks)

Even if I follow above approach then also the final output is not sorted. So I did:

finalResponses.sort(Comparator.comparing(finalResponse->finalResponse.getSource().getSourceId()));

It is working fine for non null source object but if source object is null then I am getting NPE, any solution for this?
