After creating about 2,000 vnf instances from a single model, AAI GET queries
slowed down drastically (this is using the dublin release). Comparing the
creation times in SO-monitoring, the first instance took around 2 minutes to
complete, while the 1,000th took closer to 10 minutes. This slowdown was almost
entirely due to querying AAI.
>From inspecting the logs, we saw that the GET requests that were slowing down
>were fetching relationship lists of increasing size as each newly created
>instance would be added to the next relationship list.
For example, the following curl command:
curl
https://aai.onap:8443/aai/v15/cloud-infrastructure/cloud-regions/cloud-region/CloudOwner/RegionOne?depth=2
--header 'Accept: application/json' --header 'Content-Type:
application/json' --header 'X-FromAppId: robot-ete' --header 'X-TransactionId:
12345' --header 'Cache-Control: no-cache' --header 'Authorization: Basic
YWFpQGFhaS5vbmFwLm9yZzpkZW1vMTIzNDU2IQ=='
Returns an ~800,000 character response, of which it seems like the
line-of-business-name is the only field that is needed:

Has this behavior been seen before? Is there a way to exclude the relationship
lists from the query?
Any help or insight would be appreciated.
