Creating and managing scheduled jobs Creating and Managing Scheduled Jobs Using SQL Statements This section describes how to create a job, view job details, start a job, stop a job, modify job attributes, and delete a job. Parent topic: Database Use
Default value: 1 time_to_target_rpo Parameter description: Specifies the maximum time_to_target_rpo seconds from the time when an exception occurs on the primary cluster to the time when data is archived to the OBS recovery point in dual-cluster remote DR mode.
If parallel restoration is enabled, all primary and standby replicas will simultaneously download backup data from the OBS server. Compared to serial restoration, this process demands a multiple of the bandwidth from OBS equal to the number of replicas in each shard.
Value range: Boolean on indicates that the query covering the OBS is accelerated based on the cost when the computing resource pool is available. off indicates that no query is accelerated using the computing resource pool.
Default value: 1 time_to_target_rpo Parameter description: In the remote DR mode of dual database instances, set the allowed time_to_target_rpo seconds from the time when an exception occurs on the primary database instance to the time when data is archived to the OBS recovery point

Querying GaussDB backups GaussDB backup files are stored in OBS buckets and are not visible to you. Specification changes Before you change the instance specifications, ensure that the instance is available.
Value range: an integer ranging from 0 to 2 For details about how to modify this parameter, see Table 1. 0 indicates that no DR relationship is established. 1 indicates that the OBS DR relationship is established. 2 indicates that the streaming DR relationship is established.
