Recently I was performance tuning and optimization for a customer and working on SELECT INTO statements code blocks. I saw a weird behavior and a self learning hit when I saw something interesting. In SQL Server 2014, this command seems to be running in parallel. Cool and a must from performance point of view. To reproduce this simple learning, I executed the below query on my SQL 2014 CTP2 box:
Sometimes, there are these nifty tiny features that get added to the product that we stumble upon by accident. Since my TempDB is in compatibility of 120 (SQL 2014), I thought of making an interesting test. I changed my compatibility level to 100 for AdventureWorks and did the test again. To my surprise I saw the Parallelism is gone !!! Woot, that was quite a learning.
Do let me know if you get the same behavior on a pre-SQL 2014 box.Share this article
