DVReleaseMigrationPhase enum

Where one expand/contract migration stands, as the release section numbers the deploy's choreography.

Ordered: a later phase has done everything an earlier one did.

Inheritance
Available extensions

Values

expanded → const DVReleaseMigrationPhase

The new shape exists alongside the old one; nothing reads it.

dualWriting → const DVReleaseMigrationPhase

Generated model code writes both shapes; reads stay on the old one.

backfilled → const DVReleaseMigrationPhase

Existing rows have been copied to the new shape.

verified → const DVReleaseMigrationPhase

Every chunk agrees on both shapes, and reads have not moved. Every release that reads the old shape is still a safe rollback target.

readSwitched → const DVReleaseMigrationPhase

Reads have moved to the new shape. The old shape is still written, so a release that reads it is still a safe rollback target.

contracted → const DVReleaseMigrationPhase

The old shape is no longer kept current: it has stopped being written, or has been dropped. No release built for an earlier phase can read it.
