  • Oh oh. The words you do not ever want to appear on your customers’ screens:

    “Please stand by for a few moments. Our database system is currently scaling up to meet the demand of a recent surge in traffic. The site should be operational again in a few minutes. Thank you.”

    These are the exact words Modern Hiker had to push out to their website visitors last week.

  • NuoDB is sponsoring a pair of independent and informative breakfast events called “Sharing Experiences in Cloud Adoption.” These events are an opportunity for CTOs, Chief Architects and other technology leaders to network and share insights on cloud adoption with colleagues and industry gurus.

    Pre-registration is required as seating will be limited at both venues.

  • About a year ago, we issued NuoDB Starlings Release 2.0, a major release for NuoDB. Since then, we’ve issued several point releases, most recently 2.0.4 in May.

    With NuoDB Swifts Release 2.1, we’re shipping a number of important enhancements and performance, scalability, and quality improvements.

    Connecting the dots through these releases, you’ll see a number of common themes. And with this release, we’re also plotting a path forward for the next year.

    The first theme that we’ve been refining is the concept of Automation. First

  • Ever wonder why your Sequence numbers in NuoDB are not necessarily assigned in sequential order?

    Sequences can be used to auto-generate unique values, such as the primary key column of a table. Sequences also do not respect transactional isolation so they will not cause conflicts if multiple transactions are using the same sequence at the same time. This is why using a Sequence is better than manually maintaining an integer column of a table to assign values.

    For a distributed database like NuoDB, the challenge is to ensure that every request for the NEXT

  • Earlier this week, Fortune Magazine named NuoDB CEO, Barry Morris, a 2014 Big Data All-Star , as someone who they deem as “the best at connecting the dots, digging deep, and discovering the information that will transform the way businesses operate.”

    Barry has attracted quite a bit of big data buzz recently. He’s commented on the definition of big data, pondered the possibility of

  • Seemed like a simple Jira, an easy bug fix to check off my list - a problem with our JDBC PreparedStatement#setByte(). What followed was the proverbial can of worms. I started to think about and overthink BINARY data. How is it used? What is stored in BINARY fields? How do people insert data into BINARY fields?

    I found the behavior of NuoDB to be odd, not necessarily wrong, but odd.

    First of all, it's worthy to note that one way NuoDB differs from other SQL databases, is that BINARY and VARBINARY (or BINARY VARYING) are synonyms. Any BINARY string in NuoDB is variable

    For some companies, especially large ones, the big attraction of the cloud is cost. The simple fact is that data centers are expensive to build and expensive to run. Of course cloud data centers are expensive to run too, but the big cloud vendors got going at a propitious time. They got to choose where to locate their data centers - in cooler climates close to sources of cheap electricity in areas where labor was relatively inexpensive. If you

  • Of course, every release has criteria that need to be met. In the case with NuoDB 2.0.4 the criteria were simple, and rooted firmly in product quality and stability. Sure, we may say it often and you might consider it a given, but quality was truly our sole focus for this release. We dropped nearly everything from our queue that didn't have a direct and verifiable impact on it. This investment in quality has a cost, one that we accept and embrace, because it has a lasting longer term value for NuoDB and for you. We'll consider the criteria met

  • NuoDB CTO, Seth Proctor , sat down with Roberto Zicari of ODBMS.org to discuss big data, common customer use cases and the technical features currently under development at NuoDB.

    Here are some of the highlights of the conversation.

    What is your current product offering?

    “NuoDB 2.0 is a webscale distributed database providing standard SQL capabilities for applications that need to operate in a cloud model. SQL ’92 support (

  • With our latest release cycle we faced a problem that impacted extremely load intensive long running (multi-day) tests. The symptom was a slow but steady increase in Resident Set Size (RSS) that impacted both our Transaction Engines (TEs) and Storage Managers (SMs). On large machines unless you're looking at "ps" stats you wouldn't notice it, but on typical cloud hardware the OOM killer would take out the NuoDB processes.

    Since our system is
