SQL Server has been released to manufacturing with general availability set for April 1st. Through this week we’ll be covering various aspects of the new release starting with data warehousing.
Espresso Logic has added RESTful endpoints for SQL stored procedures to their DBaaS service.
Google have announced general availability of their Cloud SQL service. At launch the service comes with automatic encryption of customer data, a 99.95% uptime SLA and support for databases up to 500GB in size.
Indexes in SQL Server’s In-Memory OLTP don’t work exactly like normal indexes. This isn’t necessarily a bad thing, but the differences need to be kept in mind to avoid performance problems.
Presto, a technology from Facebook enabling interactive SQL queries on petabytes of data, has now taken a first step into mainstream adoption. Big Data startup Qubole has launched its Presto-as-a-Service alpha with integration to Amazon Web Services.
OpenAccess ORM Q3 2013 SP1 Adds VS 2013 Support, Discontinued Classic Wizards, Oracle 9i and MySQL 5
The recently released OpenAccess ORM Q3 2013 SP1 by Telerik has introduced support for Visual Studio 2013 in addition to extended support for Visual Studio 2008. Moreover, support for classic wizards, Oracle 9i and MySQL 5.0 will be discontinued beginning with the next release of OpenAccess ORM.
With Facebook recently releasing Presto as open source, the already crowded SQL-in-Hadoop market just became a tad more intricate. A number of open source tools are competing for the attention of developers: Hortonworks Stinger initiative around Hive, Apache Drill, Apache Tajo, Cloudera’s Impala, Salesforce’s Phoenix (for HBase) and now Facebook’s Presto.
Opserver is an open source monitoring solution, released by StackExchange, of StackOverflow's fame. Opserver provides a quick overall view of each monitored system's health, while allowing the user to deep dive using a drill-down approach. InfoQ talked with Nick Crave, one of Opserver’s creators, for additional insight.
New version of Cascading released this week incorporates Hadoop 2 support and includes Cascading Lingual - an open source project that provides a comprehensive ANSI SQL interface for accessing Hadoop-based data
Facebook has open-sourced Presto, their distributed SQL query engine. Presto uses a pipelined architecture rather than the Map/Reduce design found elsewhere. In production since early this year, Facebook has since “deployed in multiple geographical regions and [they] have successfully scaled a single cluster to 1,000 nodes”.
New database developments indicate a return to SQL, but not by running the traditional relational stores on bigger and better hardware, not even on sharded architectures, but through NewSQL solutions.
NuoDB has announced version 2.0 of their NewSQL database, now a globally distributed database that can run in the cloud or on premises with real-time replication.
One of the biggest challenges when researching a new technology is determining where to start. A typical SQL Server installation could easily have hundreds of tables. Examining each one by hand to determine which would benefit from conversion, is a daunting challenge. This is where the AMR Tool comes into play.
In this report we look at the internals of SQL Server’s In-Memory OLTP to see how it uses timestamp-like transaction ids in lieu of locks.
