JVM monitoring vendor Plumbr has added slow query detection to its flagship product. With this addition, Plumbr now detects four types of problems: Memory Leaks, Garbage Collection Inefficiencies, Locked Threads and Expensive JDBC Operations.
SQL Server 2016’s new Temporal Table feature makes it easy to work with data that needs to be versioned.
SQL Server 2016’s new stretch database feature promises to offer local server performance for hot data and cloud storage for old data without any change to the application.
In SQL Server 2014 we saw the introduction of Natively Compiled Stored Procedures. In 2016 we’ll be able to do the same for Scalar User Defined Functions.
Memory Optimized Tables promise significant performance gains, but tend to be difficult to work with. SQL Server 2016 reduces much of the pain by offering ALTER TABLE support.
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.
