What’s New in Microsoft SQL Server 2014 Plaster Group Technology Management Consulting

The code executed will be in the form of stored procedures. This enables the SQL developers to just get the procedure and execute without having to worry about the code, while the data-scientists can take care of the written scripts.

Buffer Pool Extension – SQL Server 2014

SQL Server performance is influenced by factors like server hardware, operating system setup and database configuration. SQL Server provides a comprehensive set of tools for monitoring its own performance, but many SQL Server DBAs, developers and application support teamschoose to use third-partyperformance monitoring tools. Creating a buffer pool extension for SQL Server 2014 is like being able to define a different page file in Windows.

• If you run out of memory – well, let’s just say you’d better pray you don’t run out of memory, because hello, downtime.
• You can also verify that product version is similar after the upgrade as well.
• There are multiple improvements made on the Always On Availability Group.
• Once created, RDL files can be rendered in a variety of formats, including Excel, PDF, CSV, XML, BMP, EMF, GIF, JPEG, PNG, and TIFF, and HTML Web Archive.
• Data virtualization allows queries across relational and non-relational data without movement or replication.
• You should plan the required edition before installing SQL Server.

Windows and Hyper-V have supported this for a while , and now SQL Server supports it too. The big benefit here is that if one node of the SQL Server cluster loses connectivity to the storage, it can still read and write data over the network to a different node’s SAN connection. The OLTP tables are copied to memory and are made durable by writing transaction logs to disk. Also, the new engine has an improved lock-free mechanism that can process transactions for the in-memory tables. Generated Script files of the database changes are made to stored procedures or views.

There is no Cluster manager used in a Read-scale availability. Scalar UDF Inlining is adopted to bring larger performance gains. This mainly deals with transforming the scalar UDFs into equivalent relational expressions, which are “inlined” into calling the query. Adaptive joins in Batch Mode to dynamically select a join type during the runtime or execution time, based on the input rows. The heavy log generation due to the cumbersome index creation operation can be handled by pausing the index create operation, truncating or taking the backup of the log and then resuming the same. This is the feature that allows an index to create operation to pause and resume later, right from the point where the operation failed or paused, instead of starting the process all over again.

In this article, we explored different SQL Server editions and fundamental differences in these. We also used an edition upgrade wizard to upgrade SQL Server edition. We cannot use this wizard to downgrade SQL Server edition such as enterprise to standard. We can consider it edition in between the standard and express edition. It has very limited compute and feature availability and suitable for small web site hosting. The big data cluster is made of the SQL Server and Spark Linux containers.

UTF-8 Support

I prefer that they keep it a bit longer as I am more familiar with it than AGs; especially for those who are not on 2012 yet. Someone mentioned deprecated features, can’t be too long before Mirroring is removed. Do business requirements force you to use shared storage or magnetic local storage? There have also been some changes in terms of security permissions for SQL Server 2014. For more information on this please reviewthis article on Resource Governor Resource Pool and on one how tocreate a RESOURCE POOL with T-SQL.

Todd – well, Microsoft needs to release new versions every 2-3 years in order for Software Assurance to make financial sense for customers. Because of that, I’d say it’s reasonable to expect it within 2-3 years after the release of SQL Server 2012. If not, start there first – memory can be used for more than just caching clean pages. Microsoft conducted extensive research into modern-day workloads and completely redesigned the Cardinality Estimator in SQL Server 2014 to improve the quality of query plans, which in turn improves overall query performance. Specific details of these changes are explored here with Microsoft’s SQL Server team. This statement has been improved and now it can be run in parallel, but the database compatibility level must be at least 110. The ALTER INDEX command ran with REBUILD has a new COLUMNSTORE_ARCHIVE compression option for your data.

Hekaton – In-Memory OLTP and Native Compiled Stored Procedures

The video tutorial sql server part 4 master dba Extension provides the seamless integration of solid-state drives as a nonvolatile random access memory extension to the Database Engine buffer pool to significantly improve I/O throughput. We have an application where we need to handle approx 1000 requests per sec and each request involves calling a stored proc which selects and inserts from the same table. So we have only one table that will grow huge and is transaction heavy.
