  • Migrating from MySQL to VoltDB

    Is there a simple solution in migrating from mySQL to VoltDB? Do I just dump .sql files and import in?

    MySQL to VoltDB

    Migrating from MySQL to VoltDB requires a little bit of re-thinking of your application, particularly with dealing with large data and at Scale processing.

    Some things to consider:
    - How do I partition my data? You want even distribution of data across your cluster.
    - VoltDB's primary interaction model is Java Stored Procedures, so for optimal performance, you will need to convert most of your MySQL SQL into Java Stored Procedures.
    - For optimal performance and throughput, make sure your queries operate on data within a single partition, in other words, strive for making a majority of your procedures single-partition stored procedures.
    - VoltDB supports an OLTP-focused subset of SQL-99, so your SQL may require some re-work.

    We've got a couple of resources to help you get going quickly with this:

    The VoltDB Getting Started Guide, here:
    The VoltDB for SQL Developers webinar, here:

    If you need help with specific portions of your application, feel free to post them in this forum.

      Hey John,
      Does VoltDB support SQL-99 now, or still just a subset of SQL-99

        We now support quite a bit of SQL now (5 years since I last responded!), see:
        Any specific SQL constructs you are interested in?
