Welcome to the NuoDB Blog

  • In the first installment of this two part series we talked briefly about the benefits of running NuoDB as a database backend for nopCommerce. If you wanted more detail, or just to see it in action, I recommended watching the on-demand webinar “ Enabling Scalability & Redundancy in eCommerce .” Today, I’d like to introduce you to some of the details for how nopCommerce was enhanced to run on NuoDB, and to provide a peek under the covers of the “Next-Next-Next” installation.

  • The Definitive ANTLR 4 Reference

    Disclosure: I received a complimentary review copy of this book.

    I would have happily bought a copy, as I have bought copies of author Ter Parr's previous books, because he writes a different kind of "compiler" book. The Definitive ANTLR 4 Reference integrates two of Parr's previous lines of thinking; it's a great introduction to the ANTLR4 parser, but even more, it's an introduction to how to think like a real-world compiler writer.

  • The NuoSQL tool, nuosql, is the command line utility for accessing data in NuoDB. There is one new option as of NuoDB 1.2 that is very useful for displaying data with very wide columns using nuosql. Then there's another new option (but you'll have to wait for NuoDB 2.0) that is useful for displaying many rows of data.

    Displaying your data is a challenge when you have very long character strings in a column or new lines in a character string column. To demonstrate this, I created a table with the following schema:

  • Hello Techblog readers!

    I'm going to talk about tuning the Linux I/O scheduler to increase throughput and decrease latency on an SSD. I'll also cover another interesting topic about tuning the performance of NuoDB by specifying storage for the archive and journal directories.

    Tuning the Linux I/O Scheduler

    Linux gives you the option to select the I/O scheduler. The scheduler can be changed without rebooting too! You may be asking at this point, why would I ever want to change the I/O scheduler? Changing the scheduler makes sense when the overhead of optimizing the I/O (re-

  • E-shops, or “e-commerce solutions,” have become quite popular in recent years. They’re especially attractive if you have a good idea, or simply great goods, because you can rapidly make your shop and then expand your business rather easily for success. One such e-commerce solution is nopCommerce . It’s free, open source (if that matters to you), and mainly based around Microsoft technologies – ASP.NET MVC, IIS, MS SQL.

    nopCommerce is a very versatile product, and not just a simple e-shop. It supports multiple

  • My name is Jiri Cincura and I was working recently in NuoDB on improving the .NET driver, mainly around Entity Framework support. But that’s not what I’d like to talk about for today. Today I’d like to talk about connection pooling. Something that’s well known for a lot of people in (not only) ADO.NET world.

    What it is? Let me tell you whole story. Opening and closing a connection is not easy. In fact it might take a lot of time. There are a few steps involved. You need to resolve the hostname to IP, open the connection physically, the server needs to

  • Introduction

    One of the new preview features of the NuoDB NewSQL DBMS 1.2 is the addition of SQL stored procedures to the toolbox that users have at their disposal. Although they don't add any new capability to the database engine, as the same task can be done by client code written in any of the supported languages (C++, Java, .NET, Python, Perl...), a significant part of the SQL community has grown used to write them mainly for performance and security purposes.

    The performance advantage can be seen when the procedure is executing several SQL statements: in fact, by running

  • You probably saw Paul's post this week announcing our 1.2 release . It's full of "previews." Why? 'Cause there are a bunch of things we've been working on quietly that are finally making it into the product. Needless to say, we're psyched about this stuff. The one preview feature that didn't make it onto Paul's list is that with 1.2 we're pulling back the curtain on our automation work.

    I've talked a lot on this blog about how easy it is to automate monitoring and management in NuoDB. I've also said that

  • Spoiler Alert!
    Details on our next GA release, NuoDB 1.2, follow below. No window dressing, just the facts, so read on...

    Our typical development cycle produces 1 "point release" every 3 months, and 2 minor "patch" releases in between. Not so this time around. We found there to be so much in new development that it merited a point designation, skipping a second patch, and the result is a bounty of feature "Preview" goodness.

    For starters, we've made significant

  • Cambridge, MA, August 6, 2013 – NuoDB, Inc., the leader in NewSQL, announced the last release of their current product version and a technology preview of some upcoming second generation features available later in 2013. The preview is contained in the free download of the new NuoDB Starlings Release 1.2.

    Product improvements in the release include support for a range of SQL functions, a preview of a unique and powerful implementation of stored procedures, and support for new drivers and frameworks.
