enum Marten::DB::Migration::Operation::Optimization::ResultType

Overview

Defines the various types of results that can be returned by a migration operation optimization.

Defined in:

Enum Members

COMPLETED = 0

A "completed" result indicates that the considered migration operation was indeed optimized and that a new set of operations should be used in lieu of the operation.

FAILED = 1

A "failed" result indicates that the considered migration operation cannot be optimized, which generally means that that incoming operation used for optimizing has a dependency to the considered operation (for example, a CreateTable operation that has a reference column to a table created by another CreateTable operation).

UNCHANGED = 2

An "unchanged" result indicates that no optimization can be done and that operations remain unchanged (for example, two completely unrelated operations that cannot be further optimized).
