Adam Machanic has a roundup of Connect items pertaining to temporal tables in SQL Server 2016:
I’ve been thinking a lot about SQL Server 2016 temporal tables of late. I think it’s possibly the most compelling feature in the release, with broad applications across a number of different use cases. However, just like any v.1 feature, it’s not without its faults.
I created a couple of new Connect items and decided to see what other things people had submitted. I combed the list and came up with a bunch of interesting items, all of which I think have great merit. Following is a summary of what I found. I hope you’ll consider voting these items up and hopefully we can push Microsoft to improve the feature in forthcoming releases.
I particularly like the idea about dropped column retention, at least as an optional feature. If temporal tables are interesting to you, click through and check out these Connect items.
