Description

Request: /api/v1/clusters/tdk/configurations/service_config_versions?fields=group_id,user&minimal_response=true&from=0&page_size=10
Response always contains 10 records or less (if there are less than 10 service configs versions). Each record has only two fields (group_id, user).
Request execution time depends on overall count of service config versions in the DB.
Example:

Items Total in the DB	Response Time
2	~140 ms
100	900+ ms
290	3+ s
750	9+ s
1000	15+ s
3000	30+ s
