Architecture

Components

A production setup of the HTTP JSON API involves the following components:

• the HTTP JSON API server
• the query store backend database server
• the ledger

The HTTP JSON API server exposes an API to interact with the Ledger. It uses JDBC to interact with its underlying query store in order to cache and serve data efficiently.

The HTTP JSON API server releases are regularly tested with the tools described under System Requirements.

In production, we recommend running on a x86_64 architecture in a Linux environment. This environment should have a Java SE Runtime Environment with minimum version as mentioned at System Requirements. We recommend using PostgreSQL server as query-store, again with minimum version as mentioned at System Requirements.
