Analyst is a tool to validate and run Analyst Query Language (AQL) scripts. AQL is an ETL configuration language for developers that aims to be:

• Declarative: the developer defines the components, how they depend on one another, and any additional synchronization (i.e. AFTER); the runtime figures out the DAG and executes it
• Intuitive: similar syntax to SQL, but any options for external programs such as MS Excel use native conventions such as Excel Ranges
• Maintainable: support large jobs and code reuse through language features like INCLUDE and EXTERN
• Extensible: use stdin/stdout protocol and pipes to write ETL logic in any language. Native support for Python and Javascript.
• Stateful: Components can persist state in an SQLite3 database unique to each job run (GLOBAL source/destination).

It has connectors to:

• MS SQL Server (source/destination)
• Postgres (source/destination)
• SQLite3 (source/destination)
• Mandrill transactional email API (destination)
• Web APIs (source)
• Slack (for logging only)
• Flat file (source)
• Console (destination)
• Built-in in-memory SQLite3 database (source/destination)
• JSON-RPC plugins (source/destination)

1. Grab the latest binary from the releases tab and place it on your PATH.
2. Create and save an AQL script.
3. Run analyst run --script <path-to-your-script>.

For a "hello world" example, try

DATA 'MyMessage' (
	[
	  ["Hello, World"]
	]
) INTO CONSOLE WITH (COLUMNS = 'Message')
