SQL Server next version CTP 1.3 now available

Microsoft is excited to announce a new preview for the next version of SQL Server (SQL Server v.Next). Community Technology Preview (CTP) 1.3 is available on both Windows and Linux. In this preview, we added several feature enhancements to High Availability and Disaster Recovery (HADR), including the ability to run Always On Availability Groups on Linux. You can try the preview in your choice of development and test environments now: www.sqlserveronlinux.com.

Key CTP 1.3 enhancement: Always On Availability Groups on Linux

In SQL Server v.Next, we continue to add new enhancements for greater availability and higher uptime. A key design principle has been to provide customers with the same HA and DR solutions on all platforms supported by SQL Server. On Windows, Always On depends on Windows Server Failover Clustering (WSFC). On Linux, you can now create Always On Availability Groups, which integrate with Linux-based cluster resource managers to enable automatic monitoring, failure detection and automatic failover during unplanned outages. We started with the popular clustering technology, Pacemaker.

In addition, Availability Groups can now work across Windows and Linux as part of the same Distributed Availability Group. This configuration can accomplish cross-platform migrations without downtime. To learn more, you can read our blog titled “SQL Server on Linux: Mission Critical HADR with Always On Availability Groups”.

Other Enhancements

SQL Server v.Next CTP 1.3 also includes these additional feature enhancements:

Full text search is now available for all supported Linux distributions.

Resumable online index rebuilds enables users to recover more easily from interruption of index builds, or split an index build across maintenance windows.

Temporal Tables Retention Policy support enables customers to more easily manage the amount of historical data retained by temporal tables.

Indirect checkpoint performance improvements. Indirect checkpoint is the recommended configuration for large databases and for SQL Server 2016, and now it will be even more performant in SQL Server v.Next.

Minimum Replica Commit Availability Groups setting enables users to set the minimum number of replicas that are required to commit a transaction before committing on the primary.

For SQL Server v.Next technical preview running on Windows Server, encoding hints in SQL Server Analysis Services is an advanced feature to help optimize refresh times with no impact on query performance.

SQL Server next version Community Technology Preview 1.1 now available

Microsoft is excited to announce that the next version of SQL Server (SQL Server v.Next) Community Technology Preview (CTP) 1.1 is now available for download on both Windows and Linux. In SQL Server v.Next CTP 1.1, part of our rapid preview model, we made enhancements to several database engine and Business Intelligence (BI) capabilities which you can try in your development and test environments.

Key enhancements in SQL Server v.Next on Windows CTP 1.1 for Analysis Services tabular models include:

New infrastructure for data connectivity and ingestion into tabular models with support for TOM APIs and TMSL scripting. This infrastructure enables:

Support for additional data sources, such as MySQL. Additional data sources are planned in upcoming CTPs.

Data transformation and data mashup capabilities.

Support for BI tools such as Microsoft Excel enable drill-down to detailed data from an aggregated report. For example, when end-users view total sales for a region and month, they can view the associated order details.

Support for ragged hierarchies in reports, such as organizational and account charts.

Enhanced security for tabular models, including the ability to set permissions to help secure individual tables.

For more detailed information about Analysis Services in SQL Server v.Next CTP 1.1, see the Analysis Services Team Blog.

Key SQL Server v.Next on Windows and Linux CTP 1.1 database engine enhancements include:

Language and performance enhancements to natively compiled T-SQL modules, including support for OPENJSON, FOR JSON, JSON built ins as well as memory-optimized tables support for computed columns.

Improved the performance of updates to non-clustered columnstore indexes in the case when the row is in the delta store.

Batch mode queries now support “memory grant feedback loops,” which learn from memory used during query execution and adjusts on subsequent query executions; this can allow more queries to run on systems that are otherwise blocking on memory.

New T-SQL language features:

Introducing three new string functions: TRIM, CONCAT_WS, and TRANSLATE

BULK IMPORT supports CSV format and Azure Blob Storage as file source

STRING_AGG supports WITHIN GROUP (ORDER BY)s

In addition, we have added support for Red Hat 7.3 and Ubuntu 16.10 to SQL Server on Linux.

For additional detail, please visit What’s New in SQL Server v.Next, Release Notes and Linux documentation.

SQL Server + Python — What’s new

Python is one of the most popular and fastest-growing languages used today. Pyodbc (Python-SQL Server Connector) is an open source Python module maintained by Michael Kleehammer that uses ODBC Drivers to connect to SQL Server. It allows you to connect from the platform of your choice to SQL Server on-premises and in the cloud. Pyodbc is also cross platform and can be installed using pip.

We recently announced SQL Server v.Next CTP1 on Linux and Windows, which brings the power of SQL Server to both Windows and — for the first time ever — Linux. You can now connect your applications to SQL Server running on Linux, Windows and macOS (with Docker).

For our Python developers, we have a few updates that will improve Python connectivity with SQL Server. Pyodbc is now:

Officially supported: You can contact Microsoft Customer Service and Support (CSS) via phone, email, Twitter, forums, etc., to report and get help with any issue.

Available in Jupyter Notebooks for SQL Server: The Jupyter Notebook is a web application that allows you to create and share documents that contain live code, equations and visualizations.Pyodbc and its dependencies ship out of the box with Juypter notebooks on Azure. To get started, go to notebooks.azure.com and create a new Python 2 notebook or follow the instructions here. Check out the code sample and paste it in your notebook’s interactive prompt to get started.

Compatible with Python 3.5 and Django 1.10 through Django-pyodbc-azure.
