With PolyBase, you can query NoSQL data like csv files stored in Azure Blob Storage or in HDInsight. However, many SQL Server systems suffer from poor performance and scalability, often caused by poordatabase design, index design and a SQL Server system improperly configured for the workload. The reason for this is that the main goal of the development process of any large-scale SQL Server project is functionality, with performance and scalability frequently treated as an afterthought. This article explains how to improve the performance of OLTP applications using SQL Server 2014 in-memory OLTP engine. This article also details what makes SQL Server 2014 in-memory OLTP engine different from other vendors in-memory OLTP engines and how to use that to your advantage.
The In-Memory OLTP allows you to move individual tables to unique in-memory structures. This increases the performance since the entire database is not placed in the main memory. Furthermore, you can convert existing stored procedures into sql server 2014 new features for dba in-memory procedures too.

- The service program receives and processes service broker messages.
- This ensures that log-ins and jobs that are stored in the master and msdb databases are always kept in sync, erasing a major headache for DBAs.
- Standard edition includes the core functionality required for most applications.
