6.2. Special Considerations for Existing Customers

Most of the new features and capabilities in Volt V11.0 do not impact existing applications. However, there are a few changes that require action for users upgrading from earlier versions. Also several deprecated features have now been removed. Existing customers should take note of of the following changes:

  • Supported platforms

    Ubuntu 16.04 is no longer a supported production platform for Volt. The currently supported operating systems for running production Volt databases are:

    • CentOS and Red Hat (RHEL) V7.0 and later or V8.0 and later

    • Ubuntu 18.04 and 20.04

  • Python 3.6 is now required

    The system requirements for Volt have been changed from Python 2.7 to Python 3.6.

  • Support for LIMIT PARTITION ROWS has been removed

    The LIMIT PARTITION ROWS clause of the CREATE TABLE statement has been removed. The USING TTL clause and scheduled tasks are the recommended replacements for this feature.

  • The deprecated @SnapshotStatus system procedure has been removed

    The @SnapshotStatus system procedure has been deleted. The @Statistics system procedure with the SNAPSHOTSUMMARY selector is the recommended replacement.
