@Entity
public class DatabaseMigrationStateSchedule
extends CrossTldSingleton
implements SqlOnlyEntity

A wrapper object representing the stage-to-time mapping of the Registry 3.0 Cloud SQL migration.

The entity is stored in SQL throughout the entire migration so as to have a single point of access.

CACHE

public static final com.github.benmanes.caffeine.cache.LoadingCache<java.lang.Class<DatabaseMigrationStateSchedule>,TimedTransitionProperty<DatabaseMigrationStateSchedule.MigrationState,DatabaseMigrationStateSchedule.MigrationStateTransition>> CACHE

Cache of the current migration schedule. The key is meaningless; this is essentially a memoized Supplier that can be reset for testing purposes and after writes.

DEFAULT_TRANSITION_MAP

public static final TimedTransitionProperty<DatabaseMigrationStateSchedule.MigrationState,DatabaseMigrationStateSchedule.MigrationStateTransition> DEFAULT_TRANSITION_MAP

migrationTransitions

public TimedTransitionProperty<DatabaseMigrationStateSchedule.MigrationState,DatabaseMigrationStateSchedule.MigrationStateTransition> migrationTransitions

DatabaseMigrationStateSchedule

public DatabaseMigrationStateSchedule(TimedTransitionProperty<DatabaseMigrationStateSchedule.MigrationState,DatabaseMigrationStateSchedule.MigrationStateTransition> migrationTransitions)

Method Detail

set

public static void set(com.google.common.collect.ImmutableSortedMap<org.joda.time.DateTime,DatabaseMigrationStateSchedule.MigrationState> migrationTransitionMap)

Sets and persists to SQL the provided migration transition schedule.

get

public static TimedTransitionProperty<DatabaseMigrationStateSchedule.MigrationState,DatabaseMigrationStateSchedule.MigrationStateTransition> get()
