HL Iroha currently uses a separate relational database (PostgreSQL) to store its state. That requires another process to start – so it takes resources and is not very efficient. In this project we offer you to try and switch a separate database to a module that would allow storing the state within the same process.
This will not only make the architecture neat, but also positively affect the performance.
Plan:
0.Do a little research: how can this be done? What key-value storage solution would work the best for storing World State View
1.Approve the solution found on stage 0
2.Refactor the code to decouple the storage and allow easier way of changing it
3.Execute the approved solution
4.Do a little research about how it affected the performance
5.Create a configuration parameter to allow backward compatibility
SQLite - one of the options that could be used
HL Iroha is one of the main Hyperledger ecosystem projects. This project will allow Iroha become faster and also provide better customisation of the WSV storage.
The ideal mentee is a university student, someone with one or two years of experience with a solid background in Computer Science, especially C++
The following skills are required:
Working knowledge of C++
Understanding of relational databases
With this refactoring, new options of WSV storage could be implemented and more projects could benefit the improved performance
This project can be done by a full-time or part-time mentee.
