Allow large queries to be split up into manageable pieces

If I build a view in the Integrator that asks the Data Archive for a large amount of information my query can timeout. This will result in the Integrator writing NULL values to certain columns of my view. As a current workaround I just build a view that spans a shorter time frame to decrease the amount of data I ask for in my query to avoid NULL values. I then can use the Update Data functionality to additional time frames in manageable pieces. This is not ideal and I do not believe it was the intended use of the functionality. I would like to see a way to easily split up queries so that I don't timeout on the Data Archive. This may be related to this request here (https://feedback.osisoft.com/forums/555136-pi-integrators/suggestions/35539519-throttle-data-archive-reads), but is more a way to handle this issue as a user.

    Has a Tech Support case been opened about this? If the PI Integrator is writing NULL values where values were not supposed to be NULL, this is a bug and we will need to properly document/investigate this for fixing in a future release.
