1 | AAI Resiliency | ESR |
Open |
| 6th Dec 2018 | ESR in Dublin will be bug fix and non-functional requirements. Should ESR use AAF for RBAC in Dublin? Clients of ESR are MultiVIM and VF-C External system passwords are not encrypted in AAI During registration of cloud-region, ESR calls multi cloud, but when user is deleting data from the port ESR does not call multi cloud but should (feature request?) | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

38 | aai-cassandra performance issues | Keong Lim |
| Michael O'Brien has documented performance issues in aai-cassandra:
hector has discovered that the stress test jar (liveness probe?) in aai-cassandra is hammering the cpu/ram/hd on the vm that aai is on - this breaks the etcd cluster (not the latency/network issues we suspected that may cause pod rescheduling) Is there something that should be tweaked in AAI config? Or documentation on the recommended setup to run the VM? I'll come to the next AAI meet (conflicts with pomba meet) -

510 | Purpose of fields in AAI |
| Dénes Németh wrote in
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? 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?

611 | Postel's Law / Robustness Principle for AAI data inputs | Keong Lim |
| 6th Dec 2018 | While helping UUI team to debug a family of related issues such as
vs
Initially, I thought this could be due to XML-to-JSON translation error, but it could also have been a copy-paste from the output of a GET, e.g.
In the spirit of Postel's Law ("be liberal in what you accept"), could/should AAI accept both variations of the input data above? There could be additional validation that the element name inside the request body matches the element name in the URL of the API (similar validation is already performed for the key ID value). It would also allow for simple methods of data transfer/migration, where AAI output is directly accepted as AAI input. similar validation is already performed for the key ID value). It would also allow for simple methods of data transfer/migration, where AAI output is directly accepted as AAI input. 7th Dec: As per Jimmy's comment below, the difference between the "Not Accepted Input" and "Expected Input Format" is the behaviour controlled by "SerializationFeature.WRAP_ROOT_VALUE" as described in:

1318 | Relationship between POMBA Common Model and AAI schema? | Keong Lim |
| Under POMBA Common Model, Geora Barsky and Sharon Chisholm discuss objects that seem to overlap the AAI schema:
Curious to know what is the relationship between the POMBA Common Model and the AAI schema? There seems to be an overlap in these object definitions and relationships. Is POMBA a potential client for AAI schema services? 15th Nov: As per Geora's and Sharon's comments: POMBA is a client of AAI APIs. It retrieves certain objects from AAI and transforms it into POMBA COMMON model which is aimed to represent flat structure of service instance representation. and The POMBA model enables us to normalize data from different data sources to facilitate auditing. To save time and work, we often use A&AI as our starting point, but conceptually, this model can have more than is currently or makes sense to have in A&AI. So, POMBA needs to evolve independently of AAI, even though it has common ancestry. As we are having discussions about the AAI Schema Services with a view to future dynamic schema updates, e.g. via SDC modelling, we will need to be aware of the downstream impacts of such a change. I think this needs to be added to the use cases for AAI Schema Services (and GraphGraph?) behaviours. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
1419 | HAproxy in OOM |

1520 | Modeling team R4 discussion, including extra AAI attributes in a model-driven way |
| 15th Nov 2018 | Modelling team having Service Instance thoughts by Chesla Wechsler, which will affect AAI schema. Also referred from comments on ONAP R4+ Service Modeling Discussion Calls 9)“vhn-portal-url”?“Bandwidth”,"QoS","SLA",etc, attribtutes that not all the services need but still need to be stored in certain service instance: stored as a schemaless field on the service-instance vertex (Chesla will follow up) (my concerns: according to the call, is that ok if we set a "global-type of service" and a "customized-type of service", then mapped it with internal descriptor, and A&AI's model only stores global type in service instance's schema, but stores the customer-faced attributes of service in a schemaless way? Chesla Wechsler Kevin Scaggs Andy Mayer) See also Modeling 2018-11-13 The service-instance already uses a "metadata" relationship, which can store an arbitrary list of key-value pairs, but perhaps AAI should extend the use of the "properties" element, which is also an arbitrary list of name-value pairs or the "extra-properties" element, which is also an arbitrary list of name-value pairs. 15th Nov: Having seen Chesla's presentation, it should be called "Model-driven schema" rather than "schemaless" behaviour, since the idea is that the changes are controlled by SDC modelling. Seems aligned to the eventual goal in AAI Schema Service Use Case Proposals and AAI Schema Service. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
1621 | Jackson Replacement |
| 1st Nov 2018 | Security subcommittee has recommended teams move away from jackson, and will be presenting alternatives and asking for an assessment from each project. Our team will need to do an analysis - this would not be trivial, especially given how many of our repos are impacted. As of now, this would be a very high LOE for the team, we need to understand what the recommendation from the SECCOM is before we can provide better details on what the LOE would be. Updated: Using Google gson vs FasterXML Jackson 10th Oct: Present to Seccom meeting 15th Oct: Present to PTL meeting 31st Oct: Debatable whether the cost of swapping Cassandra and changing code is worth the benefit of removing Jackson from the vulnerabilities list.

1722 | AAI too slow for Holmes |
| 1st Nov 2018 | Guangrong Fu mentioned AAI in Baseline Measurements based on Testing Results:
The problem for caching is how to know when to update the cached data. Even though the access time may be fast for Holmes, the risk is using out-of-date data, so the correlations will be wrong anyway. Also, duplicating the AAI data outside of AAI is probably a bad architectural decision. Making AAI faster for these use cases would be better. Has there been a performance analysis of where the time is spent? Could it help to use ElasticSearch (e.g. as in sparky)? Should Holmes have a batch interface to get more AAI data in fewer calls? Or a better correlation API that results in fewer calls? 31st Oct: https://lists.onap.org/g/onap-discuss/topic/27805753 1st Nov:

1823 | 2 Types of logging in A&AI WS |

1924 | Disable unused web services (see also Helm chart requested values) |
| 1st Nov 6th Dec 2018 | Could we disable unused (i.e. not integrated) A&AI web services, so that the deployment is faster and the resource footprint is smaller? e.g. Champ (any other ws?) Motivation: Decrease the resource footprint for A&AI (ONAP) deployments Idea: we could support 2 different deployments 1. full (normal) deployment and 2. barebones deployment. The point of the "barebone" deployment would be to deploy only the essential services necessary for proper functioning of A&AI (leaving out services like cacher, sparky, graphadmin, having 1 cassandra node instead of 3 or 5 etc). In order to reduce hardware/cloud costs (mainly the memory footprint) it could be beneficial to support a minimalistic A&AI deployment. 1st Nov: Venkata Harish Kajur and Pavel Paroulek - investigate how to disable/enable charts in A&AI so we can create a core group of pods which handle the use-cases and than extended group will all the services. Consider a group of unused/unintegrated services (like Champ). Consider other possible groups (like GUI?) | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

William Reehil wrote introduction to (proposal for?) A&AI GraphGraph
What must the solution provide?
- a generic interface to interact with the schema and edge information, so it can be accessed via end users and microservices
- ability to be configured with any schema given in the set formats (JSON for edge rules, OXM for schema)
- ability to easily communicate to an end user a node type’s attributes and edge rules when provided with a node type as input
Looks like an API to reflect on the schema from an instance in the database.
Is there some overlap with the AAI Schema Services?
Is this leveraging AAI Schema Services e.g. as client? proxy? facade? implementation detail?
Is it an alternative to AAI Schema Services?
Update: Keong Lim I do see an overlap with the schema service mainly for the retrieval of the data, but GraphgGraph will offer more on top of that(UI, NLP), during the POC code for GraphGaph there was no schema service. Implementation details can be discussed on our call for how exactly to leverage the schema service, the poc code, and where the core logic resides for this functionality.
15th Nov: Reviewed A&AI GraphGraph and agreed that there is now overlap with AAI Schema Service that should be addressed in updating the POC version.
