Millistream Database Application (MDA) version 0.9.48 released

The Millistream MDA project team is pleased to announce the release of version 0.9.48 of our open source application for updating SQL servers with data from the Millistream Data Feed.

  • The PostgreSQL driver will now use savepoints when transactions are enabled so that any data-error or duplicate key violations will not force the entire transaction to be rolled back. This also prevents MDA from entering a never ending loop on PostgreSQL if transactions is enabled an an error occurs (since MDA as of v0.9.47 will rerun failed transactions, any error here that made PostgreSQL fail the entire transaction would thus be rerun over and over again).

As earlier announced, as of v0.9.33 the database schema is developed independently of the MDA and the latest schema including upgrade scripts is available on our ftp server under the documents section  (MDA_schemas_[version].zip). As of this writing the latest database schema is v110 and is available from

Do note however that the latest schemas are only needed if you need the new columns/tables, they are not mandatory to operate the MDA!

We consider MDA 0.9.48 to be the best version of MDA available and we recommend that users of older versions upgrade as soon as possible.

MDA 0.9.48 is available for download from the following locations:

Windows users upgrade by running the installer for the new version.

Linux users who have added our apt or yum repositories can upgrade by simply issuing:

  • Debian/Ubuntu: “apt update && apt upgrade
  • Red Hat/CentOS/Amazon Linux AMI: “yum upgrade
