In many database systems, it is a requirement to grant read permission for all databases. To achieve this, there is no other way but grant read permission to each and every database. Read more http://www.sql-server-performance.com/2015/sql-server-2014-security-enhancements-user-object-permissions/
Want a broad-level technical look at Microsoft Analytics Platform System (APS), the high-performance and scalable solution built for modern data warehousing needs? If you're looking to improve your data loading and query response times (up to and beyond 100x over legacy solutions), get the details on this massively parallel processing appliance.
Experts highlight the hardware architecture and the software, and they walk you through an end-to-end demo of the appliance's power. They show you the Big Data capabilities in APS, with the included PolyBase, which can perform standard SQL queries to access and join Hadoop data with relational data. If you're working with real-time data analytics, you won't want to miss this course!
Welcome to a new year of data goodness!
To start of this year, we have a distinguished personality in the data space in Sri Lanka, along with a SQL Server MVP speaking on a couple of interesting topics at the January meet-up.
See attached image for details, and ssslug.sqlpass.org for more.
(Also, it's not required, but it would be great to hear if you would be participating: Click here to confirm)
Prior to SQL Server 2014, SQL Server used a Write Ahead Log (WAL) mechanism which means that changes are written to the transaction log before they are committed. The major advantage with this mechanism is that there will be no data loss . However, since IO is the slowest component, there will be a high IO contention for large writes especially if you have a low performing disk configuration for log files.
Delay Transaction Durability is introduced in SQL Server 2014 to enhance write performances, read this article for more details.
Online indexing rebuilding was a major breakthrough from SQL Server to support users re-indexing while the clustered index (or table) and other indexes are available during the index rebuild operation. However, in real world there are multiple issues with these online operations as it does not have much flexibility. In SQL Server 2014, there are few options included for these online operations which is discussed in this article.
