-----------------------------------
Summary: Tag: Create an api to check if a resource is already
available in database by resource input. And send tag list along with the
resource list in response of GET /service/tags/resources/paginated API
Key: RANGER-4749
URL: https://issues.apache.org/jira/browse/RANGER-4749
Project: Ranger
Issue Type: Task
Components: admin
Reporter: Anand Nadar
*1. Need an api to get the resource by resource if it exists in database.*
Case:
Suppose there already exists below tag and resource association.
PII_NAME tag is associated with (database:HR-DB, table:EMPLOYEE, column:NAME)
Now we dont know about the above resource already existing, so we are now
trying to create a new tag resource association as below
PII_EMP_NAME associated with (database:HR-DB, table:EMPLOYEE, column:NAME)
This is done using PUT /service/tags/importservicetags -> op: add_or_update
So this will result in the deletion of PII_NAME association with the resource,
and creation of PII_EMP_NAME tag associated with the resource.
So if we have this GET service/tags/resource/service/\{serviceName}/resource
api which will have the payload as
{code:java}
{
"database": {
"values": [
"HR-DB"
],
"isRecursive": true
},
"table": {
"values": [
"EMPLOYEE"
],
"isRecursive": true
},
"column": {
"values": [
"NAME"
],
"isRecursive": true
}
} {code}
we can check if this resource already exists or not.
If the resource exists, we can get all the tags associated with that
resource(in our case PII_NAME), and include the new tag PII_EMP_NAME as well
and send this in
PUT /service/tags/importservicetags -> op: add_or_update
then both PII_NAME and PII_EMP_NAME will be associated with the resource.
*2. Need the list of associated tag names for a resource in
/service/tags/resources/paginated api.*
This will get the service resources with all its associated tags in a single
api which is also paginated.
