/*
 * API for synchronizing between HMS notification events and Sentry.
 *
 * When Sentry gets updates from HMS using HMS Notifications, HMS should
 * should wait after each notification event is generated until the notification
 * is handled by Sentry This preserves the synchronous semantics of DDL statements.
 *
 * The notification synchronization API is private between HMS and Sentry and should
 * not be used by anything else.
 *
 * The API should be used in the following way:
 *
 * 1) HMS creates a notification and stores its ID in the persistent storage
 * 2) HMS sends ID to Sentry
 * 3) Sentry blocks the response until the specified ID is processed by Sentry
 * 4) Sentry responds with the most recent processed ID.
 *
 * Note that the important part is blocking in Sentry until the specified ID
 * is processed. The returned most recent processed ID is intended for debugging
 * purposes only, but may be used in HMS for performance optimizations.
