But we did learn that the average telephone call time in Italy is 4 times that of Slovenia hummm #PASSSummit
Waiting for embrace R to start and so far ::: no pirates. Which I guess is fine. #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

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
