History Tools
The history tools repo has these components:
- Database fillers connect to the nodeos state-history plugin and populate databases
- wasm-ql servers answer incoming queries by running server WASMs, which have read-only access to the databases
- The wasm-ql library, when combined with the CDT library, provides utilities that server WASMs and client WASMs need
- A set of example server WASMs and client WASMs
