  • Hi, I’m Adam Abrevaya, the VP of Engineering at NuoDB. You’ll be seeing much more from me in the way of me introducing new innovative features in upcoming releases, how we build NuoDB – i.e. insight into our engineering practices and how we test NuoDB (that gets really interesting at massive scale – 100s or 1000s of machines).

  • Welcome, concurrency-minded nuonians, to part 3 of the MVCC overview! In part 1 , we laid out the basics of MVCC and described how MVCC enables much higher concurrency than conventional read/write locks (even per row).

  • We have had an eventful and exciting few weeks here at NuoDB. The recent Wall Street Journal article, focusing on new cloud database technology and featuring NuoDB both prominently and positively, kept us smiling. It’s nice to be recognized.

    But today is a new day, and we’ve caught sight of something else to smile about. The NuoDB Community group on LinkedIn has reached over 1,000 members to date! And we’re still growing.
