Project Online with oData cloud hosted - Delta changes
It would be really helpful to have the project online database have the extra fields as posted by Microsoft this this post for hosted users: https://msdn.microsoft.com/en-us/library/office/dn794163.aspx
We pull reports from a local server for reports. We are currently having to pull 8 GB of data a night because we want the changes from the data before. Some of the tables are growing quickly causing the process to get a little longer over time. Because it takes so long any network connection issues cause us to start that table over again.
This would help any customer that wants to have a copy of their data local and report off it.
While we only get the Timephased data tables(shown in your provided link) on a weekly basis, I have put together a delta package that uses ModifiedDate(in UTC timezone, btw) off of the "primary" tables to have refreshes of data that changedand is run every half hour. Granted we have Sql Server for our reporting back-end, so once the data refreshes, it show to the users.
