Protocol

There is much thought about protocol's that can and should be used. The following should be possible:

1. One implementation for alle communication between all microservices
2. Management and control
   • Read and change configuration of the Koios cluster
   • Read status of components
   • Trigger data sync and rebalancing
3. Data communication per record
4. Data communication for total recordset (bulk)
5. Security
   • Handshake channel security
   • Communication isolation
   • Authentication and authorization with low footprint
6. Stateless layer 3, but statefull sessions with longer duration

There are three main thoughts about implementation:

• REST/json
• The SQLwire protocol of postgres
• a custom protocol

First implementation will be aiming at REST and see from there what issues might arise. First issues are:

• we need a good REST implementation for C (given that basic coding will be done in C).
• REST is optimized for stateless, where koios might not be.

However, lets just start from there.
