Owned by Vinu Kumar

Background

Present(in the year 2022) the sunbird knowledge setup is not adoptor friendly to setup/deploy. The reason is because of the cost involved in setup & complexity of the multiple DB’s invovled.

How to make knowlg micro-services easy to install & bare minimum cost to setup/deploy by any adoptor.

At present, the sb-knowlg setup requires the below DB’s

  • Neo4J

  • Cassandra

  • Redis

  • ElasticSearch

Open questions for minimal set-up

  • Why Cassandra & Redis is mandatory for smaller projects? Can’t we setup with Neo4j & ES as primary DB’s?

  • Is Redis DB can be made optional to improve the performance of caching the data?

  • What happens if we store the large data in Neo4J? Can we skip this large data sync to ES even though we store it in Neo4J?

Schema

Lifecycle

  • Separate the lifecycle with the core code of micro-services. So that any adopter can opt for the existing lifecycle or can customize it as per their need.
