Plugin command to initialize a storage plugin for the restore operation.
plugin_executable setup_plugin_for_restore plugin_config_file local_backup_dir
gprestore invokes the setup_plugin_for_restore plugin command on the master and all segment hosts during gprestore initialization phase.
The setup_plugin_for_restore command should perform the activities necessary to initialize the remote storage system before a restore operation begins. Set up activities may include creating remote directories, validating connectivity to the remote storage system, etc.
- The absolute path to the plugin configuration YAML file.
- The local directory on the Greenplum Database host (master and segments) from which gprestore reads backup files. setup_plugin_for_restore must create this directory if it does not already exist.
The setup_plugin_for_restore command must exit with a value of 0 on success, non-zero if an error occurs. In the case of a non-zero exit code, gprestore displays the contents of stderr to the user.
