SQream is declaring end of support of VARCHAR data type, the decision resulted by SQream’s effort to enhance its core functionalities and with respect to ever changing echo system requirements.
VARCHAR is no longer supported for new customers - effective from Version 2022.1.3 (September 2022).
TEXT data type is replacing VARCHAR - SQream will maintain VARCHAR data type support until 09/30/2023.
No End of Support changes were made.
Generate a back-up of the metadata by running the following command:
$ select backup_metadata('out_path');
SQream recommends storing the generated back-up locally in case needed.
SQream runs the Garbage Collector and creates a clean backup tarball package.
Shut down all SQream services.
Extract the recently created back-up file.
Replace your current metadata with the metadata you stored in the back-up file.
Navigate to the new SQream package bin folder.
Run the following command:
$ ./upgrade_storage <levelDB path>
Upgrading from a major version to another major version requires you to follow the Upgrade Storage step. This is described in Step 7 of the Upgrading SQream Version procedure.
