Cached vs realtime connection

Keong Lim

9th May 2019

Have been testing with Traversal custom queries and Resources bulkadd API.

It appears that the caching causes a delay of approx. 1 to 10 seconds between creating new objects in Resources API and observing them in Traversal API (seems to have 2 or 3 modes which are fairly consistent).

What is the reasoning for using cached rather than realtime connection mode for some clients but not others? Cache being out-of-date would seem to be a cause of problems.

There is some discrepancy in the default configs for AAI microservices:

In graphadmin\src\main\resources\etc\appprops\aaiconfig.properties:
Line 47: aai.realtime.clients=RO,SDNC,MSO,SO
In resources\aai-resources\src\main\resources\etc\appprops\aaiconfig.properties:
Line 92: aai.realtime.clients=RO,SDNC,MSO,SO
In traversal\aai-traversal\src\main\resources\etc\appprops\aaiconfig.properties:
Line 69: aai.realtime.clients=SDNC,SO,MSO

Apparently the HTTP header "Real-Time: true" can be used to force a realtime connection. Would this refresh the Traversal cache so that all clients can immediately observe new objects? (Further testing shows the cache is not refreshed; should this be raised in a JIRA bug?)

Is there some way to know how far behind a cached connection is from realtime? e.g. by observing the latest resource-version value? Would want to avoid polling the microservice.

Assuming that the "Real-Time" header has not been specified, is there any part of the response that indicates whether a "Real-Time" connection was used by default or not?

debugging Traversal custom query problem

Calling Traversal custom query with curl:

Code Block

curl --verbose --silent --insecure --user AAI:AAI --header 'Accept: application/json' --header 'X-TransactionId: testaai' --header 'Content-Type: application/json' --header 'X-FromAppId: AAI' --header 'Real-Time: true' --upload-file data-customquery-count-vnf.json https://<IPADDR>:30233/aai/v14/query

Request body for PUT is:

Code Block
{ "start": [ "network/generic-vnfs/generic-vnf/test-bulkadd-gvnf-4" ], "query": "query/count-vnf-byVnfType" }

Response returns error:

Code Block

{
  "requestError": {
    "serviceException": {
      "messageId": "SVC3002",
      "text": "Error writing output performing %1 on %2 (msg=%3) (ec=%4)",
      "variables": [

        "ERR.5.4.4000"
      ]
    }
  }
}

Stored-query definition appears to be:

Code Block
"count-vnf-byVnfType":{ "stored-query":"builder.getVerticesByProperty('aai-node-type', 'generic-vnf').groupCount().by('vnf-type').store('x').unfold()" }

How do I debug/fix this query?

9th May: Venkata Harish Kajur could you take a quick look at this and email me?

Keong Lim This custom query seems to only support one format which is the console. The reason is the output of this query just return a list of counts grouped by vnf type. It doesn't make sense to be able to support any other format. The default format I believe is the graphson so thats why its failing. Add the query parameter format=console and it should fix this issue. We should probably update the documentation to say that this custom query will only be working with format=console

AAI Modeling Multi-part key for schema elements

Keong Lim

title	In Progress

25th Apr 2019

From https://lists.onap.org/g/onap-discuss/topic/31317665

Discussion:

The cloud-region schema element is unusual in that it has a two-part key i.e. "cloud-owner" and "cloud-region-id". There are not many other usages of it ("ctag-pool" , "service-capability" and "route-target" are three others, out of over 100 other schema elements)
Is it possible to enhance the error message to indicate that part of the key value is missing from the relationship-data?

Is it time to deprecate the relationship-data and switch over to using the related-link only?
Is there any modeling guidance that would steer new designs away from using multi-part key for schema elements?
Are there other caveats to using the multi-part key design for schema elements?
Can we get feedback from Chandra Cinthalaon the key design for multi-part keys and whether this will be more common going forward?

Keong,

I think we have no plans to deprecate the relation-data option the in the A&AI relationship payload.
It's another option for the client to specify the relationship.

Thanks

Potential issues:

fragility of static import data file w.r.t. schema changes and version upgrades for each ONAP release?
how "common" is this knowledge, i.e. what to load, where to get it, who else should be using it, etc?
should it be automated/scripted, rather than manual steps to bootstrap?
should it be a simulator program or test harness, rather than a static data file?
should it reside within AAI CI/CD jobs for maintenance and upgrade of schema versions?
who maintains the data itself? Is there a "data repository" which can be delegated to other teams, e.g. like documentation repository links in git?
how many other teams have similar private stashes of AAI bootstrap data?
does it need to be published at a stable URL to avoid linkrot?

Possible solution/action:

Look at the examples API and possibly enhance it to get the desired behavior
Collect all the known data samples, commit to test-config repo, update the teams/wiki to point to test-config repo instead of keeping private stash of AAI data

Purpose of fields in AAI

:

In think it would be good to answer what is the meaning of the field (collection of PEMs of the CA xor URL)

Questions:

1. Is AAI intended to strictly prescribe how the fields are used and what contents are in the values?
2. Or does AAI simply reflect the wishes of all the client projects that use it to store and retrieve data?

Even if (1) is true, AAI is not really in any position to enforce how clients use the data, so really (2) is always true and we need to consult the original producers of the data and the ultimate consumers of the data to document their intended meanings.

How do we push to have documentation on the purpose and meaning of the fields in AAI?

Where does all this documentation go?

Should the documentation be backed up by validation code?

Schema-service roadmap

James Forsyth

Former user (Deleted)

Status

title	On Hold

21st Mar 2019

31st Jan 2019:

The schema-service is ready. Currently it provides file-sharing capabilities in terms of schema/edgerule files.

In order for GraphGraph to take advantage of the schema parsing/processing in schema-service additional abstractions have to be implemented on top of the crude file2string functionality currently in schema-service.

Venkata Harish Kajurwill ask Manisha Aggarwalif the current functionality of the schema-service is the final version for Dublin and if there will be further enhancements in next releases.

GraphGraph needs the following functionality:

Venkata Harish Kajur and Manisha Aggarwal What is missing in schema service that is needed in graphgraph is the following:

rest call to get available schemas
list of all schema nodes/items (like vserver, tenant, p-interfaces..) for example on a REST path /schemas/{schema}/nodes
all relevant attributes of a given node/item for example on REST path /schemas/{schema}/nodes/{node}
edges/relationships with their attributes between schema nodes/items (for example on REST path /schemas/{schema}/edges where you specify a "from" "to" schema items as query params)
subgraph of the schema, where you specify 1. initial (root) items/node (like tenant or vserver) 2. schema version and 3. number of parent/cousin/child hops from the initial item/node
all paths in a given schema graph between 2 items/nodes (like vserver and tenant) for a given schema version
edges in the schema graph should be composed of edges in the schema file + edges created from the edgerules file
edges should contain basic attributes when delivered via the subgraph call (like parent/child relationship and important properties from edgerules) and have additional (or all) attributes when queries via /schemas/{schema}/edges REST endpoint.

20. Mar 2019:

Open questions for schema-service:

what is the current implemented functionality?
what are the business use-cases in ONAP for schema-service? Description of functionality in relation to other services/projects is needed. In other words who needs it and why?
if no business use-cases can be formulated we should consider removing schema-service from A&AI and replacing it with standard file-sharing mechanisms.

21st Mar 2019:

Based on William Reehil comments

https://wikilf-onap.onapatlassian.orgnet/wiki/display/DW/AAI+Schema+Service?focusedCommentId=45299262#comment-4529926216325457 what is "our future proposed functionality"?
