TitlePluggable mechanism for StateDB and Ledger Files using MongoDB
Status

CANCELLED

Difficulty

 MEDIUM  

Description 

Presently, Fabric stores StateDB in CouchDB or goLevelDB. Create a pluggable mechanism for StateDB using MongoDB. Also, create a pluggable mechanism for storing ledger files in a database such as MongoDB. This mechanism will not only help make data stores truly pluggable, but also make easy to analyze Hyperledger Fabric data natively using MongoDB. Analzying Fabric data (e.g., for provenance) is currently a huge challenge and requires creation/setup of a separate infrastructure.

Additional Information

  • See FAB-6263 - Getting issue details... STATUS
  • See last year's project on blockchain-analyzer which retrieves and stores the Fabric data in a separate data store for better analysis. This approach requires a separate copy of Fabric data, which creates a storage and operational overhead.

Learning Objectives

  • Hyperledger Fabric code
  • Go, Docker
  • Weekly 1-1 meetings, Slack
  • Code as lab
  • Incorporate code in mainline Fabric

Expected Outcome

  • Hyperledger Lab demonstrating the feasibility
  • Incorporating the code into mainline Fabric code

Relation to Hyperledger 

Hyperledger Fabric

Education Level

Undergraduate or graduate

Skills

  • Go, Docker
  • Familiarity with Fabric (creating a network or starting a dev environment) is a plus

Future plans

Incorporate the project source code into Hyperledger Fabric

Preferred Hours and Length of Internship

40 hours during summer
