EmmyMiao87 opened a new pull request #5299:
URL: https://github.com/apache/incubator-doris/pull/5299
## Proposed changes
1. Support backup and restore view and odbc table. The syntax is the same as
the backup and restore table.
2. If the table associated with the view does not exist in the snapshot,
the view can still be backed up successfully, but the TableNotFound
exception will be thrown when querying the view.
3. If the odbc table associated with the odbc resource, the odbc resource
will be backuped and restored together.
4. If the same view, odbc table and resource already exists in the database,
it will compare whether the metadata of snapshot is consistent.
If it is inconsistent, the restoration will fail.
4. This pr also modified the json format of the backup information.
A `new_backup_objects` object is added to the root node to store backup
meta-information other than olap table,
such as views and external tables.
```
{
"backup_objects": {},
"new_backup_objects": {
"view": [
{"name": "view1", "id": "10001"}
],
"odbc_table": [
{"name":"xxx", xxx}
]
"odbc_resources": [
{"name": "bj_oracle"}
]
}
}
```
5. This pr changes the serialization and deserialization method of backup
information
from manual construction to automatic analysis by Gson tools.
