Aptos Move Module Function Indexer

Without adding new tables/processor on native aptos indexer, fetches module data from indexed database, parses functions and index them.

Setup

1. Install Rust: https://www.rust-lang.org/tools/install

2. Setup Diesel ORM:

   sudo apt-get install libpq-dev
   cargo install diesel_cli --no-default-features --features postgres

3. Edit values in .env file, Postgresql only.

   • DATABASE_URL: Database of function indexer
   • FULL_INDEXER_URL: Database of native Aptos indexer

4. Diesel migration

   cd crates/database 
   diesel migration run 
   

Logs

There are three different types of log on the runtime.

• fetch_module_task(query modules from aptos native indexer)
• parser_task(parse functions from modules)
• function_indexing_task(insert functions to db)

These tasks run in asynchronous manner and pass data through crossbeam-channel
