How are you going to use Power BI? With the service? I was wondering, the article mentions performance improvements for columnstore indexes in SQL Server What is the tradeoff?
The suspense is killing me! What will be the impact for us. I just came across this as I am investigating the upgrading of a couple of boxes. Thank you for your thoughtful and informative post. My question is do you have the same opinion now that it is almost a year later than when you wrote this.
Clay — have any versions of SQL Server been released since the post was written? If not, why would my opinion change? Actually I would prefer because that would make my versions consistent across multiple servers. I was able to configure and test almost without issues the windows Cluster, Quorum for it, AG, including failing over from Primary to secondary.
Also created Listener and tested it. Can anybody confirm or tell me where to look? Thank you. Good Post, But my opinion is please be using SQL server and it is consider as most stable database engine. All of their latest versions are just a fancy wordings. But none of them are working as per the expectations. We recently faced a count query issue on our largest table after creating non clustered column store index. The table actual row count was 1 billion but after index creation it returned with 40 billion as a count.
We will not accept mistakes in basic things like select count with incorrect results, this will impact the business. Still SQL server have no improvement in table partitioning, still always on supports with full recovery model, enabling legacy estimator in database scoped configuration for queries running well in older database version. Running durable memory optimized count query result duration is similar to normal table count duration. When comes to large volume those fancy will not work as per the expectations.
We are using SQL server sp1 enterprise edition. The problems we are facing are our realtime issues, those are not received by surfing any websites. When come to performance majority of the stored procedures are running behind and in Thanks for agreeing.
When we are planning to go with latest version the features projected by product vendors will not produce incorrect results. Cardinality estimation is one of the major problem. We have objects works well up to after execution durations increased and tempdb and db logs are running out of storage, enabling legacy estimation on or change db compatibility level to resolving our problem. Now SQL server released and also preparing for In that case we all prefer to go with , think about companies migrated to will pay additional cost for Microsoft should consider their customers when releasing latest versions.
Releasing cu is different than version release. If possible kindly refer niko post and search my name I was describing my problem and niko also agreed.. So — I made that happen. You can click Consulting at the top of this page for that kind of help.
Hi Timothy King, No need to fear about end of support. As a Microsoft SQL Server DBA , we raised a support ticket to Microsoft support team for a major bug in non clustered column store index in version SP2 due to our internal security policies restrictions we are unable to bring the support team to diagnose our server. Because the team will install some diagnostic software and collect logs from our server, as per the policy we have so many restrictions and unable to proceed further, in that case we are unable to utilize the support.
Better to use a stable version of SQL server, I believe or consider as a stable versions, to my experience new versions of SQL server are concentrated in cross platform technologies for analytics workload, most of the existing queries running well in are running with degraded performance due to the latest cardinality estimation and optimizer enhancements, Even Microsoft accepted this as a bug and provide workaround like this, enable legacy cardinality estimation on, use query hint for the specific query blocks, change sql server compatibility to something like this.
But one thing we need to consider in future if there is very limited scope to bring other data source data for processing in your environment means we can run with older version of SQL server. Existing features requires lot of improvements but Microsoft is not looking such things and releasing versions like a movie.
If i am explains multiple items then people may thing i am surfing from internet and write those but not like that these are all our real time issues we faced. Please stick with your stable SQL server version for your continuous application support without any escalations. A year later, is the your advise still to stay with SQL?
For example, how many people actually know what the permanent changes to TempDB in the form of making TF functionality no longer optional for TempDB are? All 8 files automatically tried to grow to 25GB. The only way to recover that space is to rebuild the related heap or index. The only way to overcome the problem without changing code is to use TF We have SSRS reports too.
Also, do you recommend using compatibility mode? No much to gain but can upgrade by changing the compat mode. Love to hear your opinion on this. There are no new features we wish to take advantage of at this time , just want to push out the time to the next upgrade , hot diggity! I am the DBA so would like to go , but dev feels we should go to It reminds me of the RTM for , which was just awful. Thanks for your post, Brent. Windows Server Essentials documentations.
