Solana AccountsDb Plugin Interface

This crate enables an AccountsDb plugin to be plugged into the Solana Validator runtime to take actions at the time of each account update; for example, saving the account state to an external database. The plugin must implement the AccountsDbPlugin trait. Please see the detail of the accountsdb_plugin_interface.rs for the interface definition.

The plugin should produce a cdylib dynamic library, which must expose a C function _create_plugin() that instantiates the implementation of the interface.

The solana-accountsdb-plugin-postgres crate provides an example of how to create a plugin which saves the accounts data into an external PostgreSQL databases.

More information about Solana is available in the Solana documentation.
