SQL Hax0r, 1st ever DBA at Sybase, now tracking cancer with Microsoft SQL Server

Don’t cancel my acct eloon


But we did learn that the average telephone call time in Italy is 4 times that of Slovenia hummm #PASSSummit


Dude next to me in the Amazon talk is falling asleep. We did just have lunch,,, #PASSSummit


Uh oh our analytics speaker is missing!! #mightneedtoBail #SQLSatRedmond


Alt-select w your mouse selects columns in sql editor! #SQLSatRedmond


You can now reorganize your clustered columnstore indexes #SQLSatRedmond


Sql keeps the col min and max in the columnstore metadata: no computing done at exec #SQLSatRedmond


Sunil is sharp and funny that's rare ! #SQLSatRedmond


Ok now downsides: Bulk load of rows in cci is fully logged. Also exclusive table lock. #SQLSatRedmond


Kalen had the second PC ever at Sybase (1st was in engineering), she *pioneered* PC tech support! Those were the days! #SQLSatRedmond

Hey #SQLSatRedmond! @benvonsql is the only person I know who's been using SQLServer longer than me. He gave me my 1st username and password.



Sql 2016 also supports snapshot isolation on clustered columnstore, enabling use of alwayson #SQLSatRedmond


In sql 2016, you can finally create a clustered cs index on a nc primary key : the pk references the columnstore #SQLSatRedmond


When you fetch from columnstore, you only need to fetch selected columns, not the whole row. That's the main benefit #SQLSatRedmond


All the data and index pages are compressed in a clustered column store you get to to 3..10x compression #SQLSatRedmond


Creating a cl CS index takes 1.8x a regular cl index due to compression. 10x faster queries up to 300x faster #SQLSatRedmond
