Clustered Columnstore Indexes were one of the two headline features for SQL Server 2014. Designed for tables with over 10 million rows, they allow for good performance on analytical queries without the need to explicitly specify indexes. With SQL Server 2016, they gain the ability to support secondary indexes.
Non-clustered Columnstore Indexes are also getting some enhancements in SQL Server 2016. The most notable of these enhancements is the ability to be updated.
New for SQL Server 2016 is the ability to place a Columnstore Index on an In-Memory Table.
SQL Server 2016 will finally see native support for JSON.
Slick, Typesafe's database query and access library for Scala, now supports the Reactive Streams API in the just released version 3.0. This enables developers to query their databases asynchronously and non-blocking. InfoQ talked to Slich Tech-Lead Stefan Zeiger to learn more about the new features and what they've planned for the future.
Continuing our MySQL 5.7 coverage from last week, we take a look at changes to security, data integrity, performance, and some new features such as Generated Columns.
MySQL 5.7 comes with over 20 enhancements to InnoDB. In this, the first of our reports on MySQL 5.7, we will cover some of the highlights such as temp table performance, spatial indexes, and full text search parsers.
A lot of small releases were made by Microsoft’s SQL Server team last month. Some of the highlights include Power BI for on-site servers, System Center support for SQL Server 2014, and updated Java/PHP drivers.
A prototype of MySQL 5.7 is shipping with an optional component called the MySQL HTTP Plugin. This plugin allows direct access to MySQL via a REST over HTTP interface, eliminating the need for a middle-tier server or database specific drivers.
FoundationDB has announced the general availability of SQL Layer, and ANSI SQL engine that runs on top of their key-value store. The result is a relational database backed up by a scalable, fault-tolerant, shared-nothing, distributed NoSQL store with support for multi-key ACID transactions.
In their latest Patch Tuesday, Microsoft issued 9 bulletins covering a total of 37 common vulnerabilities and exposures (CVE) spread across some of their products.
The second service pack for SQL Server 2012 was recently released with over 30 bug fixes since the last cumulative update. But according to Aaron Bertrand of SQL Sentry, one important hotfix for Enterprise customers didn’t make the cut.
Up until now, JetBrains’ IDEs have included plug-ins for dealing with database administration and development tasks. JetBrains has decided to extract the respective functionality and place it in an IDE of its own, namely 0xDBE.
Hadoop Summit Day Two report covers the important trends and changes from last year's summit. It also covers the important announcements of the day in relation to this year's trending topics.

In what is probably a surprise to many developers, MySQL currently stores its critical system tables in MyISAM instead of InnoDB. Since MyISAM isn’t ACID compliant, there is a chance for data loss or corruption when modifying system objects such as privilege. Morgan Tocker has announced that the MySQL team intends to address this in the near future.
