Thanks for the comment. Also, I did mention “sermon” in the post. Most sermons are more feeling than fact. But the post does contain facts, yes.

I like your approach to collecting data for this question. I’d suggest you also add in a dimension for the severity of the bugs being found. For example, a security bug would be something I consider to make a platform unstable versus a DMV returning slightly incorrect results.

The number of bugs may be a subset of all known bugs reported or found. We may never know the total number, all we know are how many get fixed. What we could be seeing is that Microsoft is able to fix many more bugs today than they did 3 or 5 years ago.

I’d also suggest you research other platforms such as Oracle to compare how well they are doing. And, when you get this done, please share your results!

Thanks

Tom

But I can offer you this one.

Since SQL Server 2017 RTM release on Oct 2, 2017 and its latest CU4 release on Feb 20, 2018, there are 176 hotfixes released (I count them in each CU and then sum them together).

select 176.0/datediff(day, ‘20171002’, ‘20180220’) = 1.25 bug found/day

Is this stable or not? I do not know.

I may write a blog later to compare sql 2017 vs previous versions and see whether “SQL Server 2017 is really stable”
