Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

application_type: Option<String>

The type of application whose candidate version was tried, echoed from the worklist entry’s application_type. Omitted by a consumer that predates the entry carrying it, in which case Canopy derives the application from the machine and the version.

data_bytes_after: i64

Size of the data after they ran. The growth between the two is what shows a migration that backfills heavily.

data_bytes_before: i64

Size of the data before the migrations ran.

failed_migration: Option<String>

The migration that failed, when one did.

target_version: Option<String>

The version whose migrations were applied, as semver, taken from the worklist entry’s target_version. This is the version the consumer actually migrated to; send it in preference to echoing the identifier.

target_version_id: Option<Uuid>

The version whose migrations were applied, as the identifier a consumer echoes from the worklist entry’s target_version_id. Accepted only for older consumers that report the identifier; omit it when target_version is sent.

timings: Vec<MigrationTimingArgs>

One entry per migration that ran, in the order they ran.

total_elapsed_seconds: i64

Whole seconds the whole migration run took.
