File Format Change

NoteThis version includes a backward incompatible file format change for YSQL. This means that if you have an existing cluster with YSQL schema, then you will not be able to connect to the YSQL database after upgrading to this version.

There are two ways to address the above note.

  • If you don’t care about preserving your existing data, then delete your cluster, and create a new cluster with 1.2.10.
  • If you want to continue using your existing data, then please save your data (in the form ofSQL statements), delete the cluster, create a new cluster with 1.2.10 and then load the previously saved data.
