That forces us to do some research about the new version’s features in order to make the most accurate decision. In-memory OLTP was introduced in SQL Server 2014, but greatly improved in SQL Server 2016. If you have a heavily-used transaction-processing that is processing a lot of data, it is definitely worth considering the new ‘In-Memory’ features of SQL Server 2016. Another new server-level permission, which when granted allows a login, for example, an auditor, to view data in all of the databases that the user can connect to. The new estimation logic which was designed for the cardinality estimator has improved the quality of the query execution plans and thus has a direct impact on the performance of queries. Use the slider controls in the small chart to zoom in on a specific time period in the chart above.
By using clustered columnstore indexes you will improve your data compression the performance of your query for warehousing workloads that mainly target bulk load operations and queries that are read-only. The Real Time SQL Monitor page shows in real time the SQL statements that are being monitored https://remotemode.net/become-a-sql-dba-developer/sql-server-2014/ in the database. In the Auto Refresh drop-down list, you can select the time (in seconds) to periodically refresh the data. For Oracle Database 12c and later databases, you can use the CDB/PDB drop-down list to filter the information displayed for the container or pluggable database.
6.4 Viewing Backup Logs
The Storage page shows the storage used based on the current allocation of tablespaces along with additional drill-down capabilities to view segments. You can refine the list of segments shown by using the filter feature. For Oracle Database 12c and later releases, you can use the CDB/PDB drop-down list to filter the information displayed for the container or pluggable database. SQL Server 2019 Big Data Clusters adds enhancements to PolyBase to improve
the data virtualization experience between SQL Server and other database engines.
- In the last version, it was known as Business Intelligence Development Studio (BIDS) and SQL Server Data Tools (SSDT) for BI.
- The SQL Server 2014 Resource Governor can limit the physical I/Os issued for user threads in a given resource pool.
- The Buffer pool extension allows us to extend the buffer pool to storage (you’ll want this to be ssd since we’re trying to speed things up).
- We can select the desired Operation system version to install SQL Server 2019.
- The new estimator has incorporated algorithms and assumptions which work with modern OLTP and data warehouse workloads.
The initialization parameter file is read at database instance startup. Database recovery can take a significant amount of time and be a struggle to complete on time due to active long-running transactions. Managing transaction log growth, so it doesn’t run rampant has also been known to cause many headaches.
6.7 Viewing Tablespace and Segment Space Usage
Leveraging the memory-optimized TempDB metadata feature will help with your TempDB bottlenecks. ADR will help you significantly reduce your database recovery times because you no longer have to wait on that one super long-running transaction and will help control crazy transaction log growth. Do you need a quick estimated distinct count on that enormous billion-row table? Always Encrypted with Secure Enclaves may be just the solution you’re looking for.
The below image shows data virtualization options in SQL Server 2019. SQL Server 2019 provides a data virtualization solution which is an improvement
to the ETL process. Data virtualization allows integrating data from different sources
such as MongoDB, Oracle, DB2, Cosmos, and Hadoop Distributed File System (HDFS)
without moving data around. Some of the features are upgraded but many of them are same in SQL Server 2014, such as replication, SSIS, or SSRS. There are many other features, which are very outdated, Microsoft discontinues from the launch of SQL server 2014, such as Compatibility level. It will be nice if this tip would have included the version that these features are supported!
Performance Improvements in SQL Server 2014
In all the earlier versions of SQL Server the SSDT BI does not allow to install SQL Server Setup in it, you have to install it separately form MS download Center. Allows logins to perform SELECT Statements in all databases that the login has CONNECT permission. For a system that uses partitions – we can now create unique statistics for each partition. This allows for improved performance when distribution of data varies between partitions. Partitions are only supported on Enterprise Edition of SQL Server 2014. SQL Server 2014 comes with a set of enhancements as compared to its processors that brings a lot of business benefits to the applications in OLTP and OLAP environments.
Data virtualization integrates data from different sources and does not need
replicating or moving the data. As shown above, a single virtual data layer delivers
unified data services that can support multiple applications. In SQL Server 2019,
we define this virtual data layer as Data hub or Data Lake. This layer also works as a data controller between multiple
data sources. As more businesses embrace remote work and cloud-based technologies, the need for remote database administration (DBA) services has increased.
We run all kinds of Database services that vow your success
It provides bi-directional integration with big data Hadoop and Apache Spark systems. We can easily manage the big data using the built-in tools with SQL Server 2019. Microsoft recently announced the preview of
SQL Server 2019 on September 24 at the Ignite 2018 Conference. Yes,
Microsoft is moving very fast with feature enhancements, improving security, performance,
enhancing the capabilities of machine learning, data integration, etc. In this tip,
we will see an overview of some of the exciting new features of SQL Server 2019.
You can also create, clone, plug, unplug, or drop pluggable databases. To encrypt database backups, all the earlier versions of SQL server need a professional utility. However, SQL Server 2014 provides an in-built database backup encryption. It also facilitates Windows Azure integration to SQL Server 2014 backup. For a while SQL Server has had a method to automatically update statistics when the database engine feels they are out of date.

For more detailed information please review the following links about Columnstore Indexes and how to use Clustered Columnstore Indexes. Columnstore indexes is another card in the suite of high-performance technologies that use in-memory processing. The Movements page enables you to monitor current and past SQL Developer pluggable database uploads to the database server. See Using Pluggable Databases (PDBs) to Load Data into the Database. The Alerts page is a chronological log of messages and errors and is commonly used to learn whether the background processes have encountered errors.
