Delete Atlas metadata for physical deletion

1. Problems

To delete Atlas metadata, Atlas components are logically deleted by default, but we want to perform physical deletion

Two, solve

1. Modify the configuration file

vim /opt/module/atlas/conf/atlas-application.properties

Add the following:

#开启物理删除
atlas.DeleteHandlerV1.impl=org.apache.atlas.repository.store.graph.v1.HardDeleteHandlerV1

2. Restart Atlas

python2 /opt/module/atlas/bin/atlas_stop.py
python2 /opt/module/atlas/bin/atlas_start.py

3. Call the AtlasAPI interface to delete

How to clean up soft-deleted entities

In Apache Atlas, is there a way to delete/clear soft deleted entities after hard deletion is enabled?

The requirements can be met through the following API:

Http request method:

----------------soft delete----------------

curl -iv -u admin:admin -X DELETE http://localhost:21000/api/atlas/v2/entity/guid/88f13750-f2f9-4e31-89f7-06d313fe5d39

---------------- than hard----------------

curl -i -X PUT  -H 'Content-Type: application/json' \
-H 'Accept: application/json' \
-u admin:admin 'http://loclahost:21000/api/atlas/admin/purge/' \
-d '["88f13750-f2f9-4e31-89f7-06d313fe5d39"]'
