Oracle NoSQL Database 2.0.39 released1

April 25th, 2013 Posted in LuxNoSQL, NoSQL
Comments Off

Oracle NoSQL Database 2.0.39 has been released and introduce several improvements, a couple of new Oracle product integration points as well as a number of important bug fixes. These new features and fixes include:

- An integration with Oracle Coherence has been provided that allows Oracle NoSQL Database to be used as a cache for Oracle Coherence applications, also allowing applications to directly access cached data from Oracle NoSQL Database. Documentation can be foundhttp://bit.ly/14e6jEP.

- Oracle NoSQL Database Enterprise Edition now has support for semantic technologies. Specifically, the Resource Description Framework (RDF), SPARQL query language, and a subset of the Web Ontology Language (OWL) are now supported. These capabilities are referred to as the RDF Graph feature of Oracle NoSQL Database. The RDF Graph feature provides a Java-based interface to store and query semantic data in Oracle NoSQL Database Enterprise Edition. Documentation can be found http://bit.ly/Y7aQX4.

VoltDB v3.2 has been released1

April 23rd, 2013 Posted in LuxNoSQL, NoSQL
Comments Off

VoltDB v3.2 has been  released and can be downloaded here: http://voltdb.com/community/downloads.php

Changes include:

  • Enhanced Support for Live Schema Updates
  • Improved Performance and Resilience of Catalog Updates
  • New Return Status for Snapshot Restore
  • hange to the Default Heartbeat Timeout

 

The following issues have been fixed:

  • Automated snapshots and node failure

    It was possible for automated snapshots to silently stop occurring after a node failed and rejoined the cluster. This did not happen all the time, but could not be corrected without restarting the cluster. This issue has been corrected.

  • The sqlcmd command and stored procedure names

    Previously, the sqlcmd command line tool could not invoke a stored procedure if the procedure name started with a SQL statement keyword, such as “select” or “delete”. This issue has been corrected.

  • Enterprise Manager fails to recognize cluster changes

    In recent versions of VoltDB, it was possible for the Enterprise Manager to start a database cluster but not recognize when the database completed startup. Similarly, if a node failed to rejoin or a recover operation did not complete the Enterprise Manager might not recognize these conditions. The symptom in all cases was that the database or server icon would not stop “spinning” in the Enterprise Manager control panel. These issues are now fixed.

MemSQL ships 2.0. Scales in-memory database across hundreds of nodes, thousands of cores1

April 23rd, 2013 Posted in LuxNoSQL, NoSQL
Comments Off

MemSQL runs on 64-bit Linux. Ideally suited for machines with multi-core processors and at least 8 GB of RAM Download MemSQL

MemSQL goal was to deliver the fastest OLTP database ever. Inspired by the scale and architectures we saw at Facebook, we hoped to help every enterprise leverage in-memory technologies similar to those that leading web companies use.

Customers like Zyngaand Morgan Stanley not only wanted to quickly commit transactions to the database, they also wanted instant answers to questions about how their real-time data compared to historical data. This inspired the MemSQL team to build something new – a solution that supports highly concurrent transactional and analytical workloads at Big Data scale.

Today MemSQL’s real-time analytics platform is available for download. This is the first generally available version of MemSQL that scales horizontally on commodity hardware. It provides the blazing fast performance for which MemSQL is known, and now does it at Big Data scale. Customers have deployed MemSQL across hundreds of nodes and dozens of terabytes of data, and we’ve tested at even greater volumes and velocities. (Check out ourcalculator to get an idea of the number of reads and writes you can perform depending on the size of your cluster.)

This is also the first version to include MemSQL Watch, a visual web-based interface for monitoring and managing your cluster. We expect this to be the beginning of our foray into real-time visualizations as many of our customers look to operationalize their analytics.

Deploying a database can be difficult, so we’ve made it as simple as possible.  for free on our site and take it for a spin. You’ll definitely be impressed by the performance, but you’ll also be impressed by what’s missing:

  • Batched loading – Don’t wait until the middle of the night to refresh your reports.
  • Complicated programming languages (and a limited talent pool) – Use SQL for real-time analytics.
  • An expensive, proprietary box (and a plan to rip and replace it in a few years) – Scale incrementally on commodity hardware.
  • A lengthy implementation cycle – Launch your first MemSQL instance in minutes in the cloud.

TokuDB open sourced and v7 released1

April 22nd, 2013 Posted in LuxNoSQL, NoSQL
Comments Off

http://www.tokutek.com/2013/04/announcing-tokudb-v7-open-source-and-more/

TokuDB Version 7, for MySQL and MariaDB is going open source.

The free Community Edition is fully functional and fully performant. It has all the compression you’ve come to expect from TokuDB. It has hot schema changes: no-down-time column insertion, deletion, renaming, etc., as well as index creation. It has clustering secondary keys. We are also announcing an Enterprise Edition (coming soon) with additional benefits, such as a support package and advanced backup and recovery tools.

Making TokuDB open source is a natural next step for Tokutek’s involvement in the MySQL community. So far, Tokutek has been involved in the community in many ways:

TokuDB v7 maintains all our established advantages: fast trickle load, fast bulk load, fast range queries through clustering indexes, no fragmentation, and full MySQL/MariaDB compatibility for ease of installation.

In addition, there are plenty of other performance improvements included in this version. For starters, TokuDB v7 adds support for Direct I/O. Also, you asked for it, you got it: TokuDB v7 has significantly enhanced Engine Status information.

For details on updates to pricing and supported MySQL and MariaDB versions, please see our FAQ.

  • Download executables here.
  • The source code is available on GitHub.
