-- Use Case: Accelerating Batch Analytics (accelerating-batch-analytics)
--
-- Speed up batch analytics with an always-on incremental Feldera pipeline.
--
-- ## Detailed Description
-- This demo converts the Spark batch job to a Feldera pipeline without
-- requiring changes to the queries.
-- Detailed description here: https://docs.feldera.com/use_cases/batch/intro
--
-- Instead of a Spark job that needs to be rerun every time the input changes,
-- with Feldera, these changes are reflected immediately in the output.
--
-- The queries in this demo are taken from the TPC-H benchmark.
--
-- ## How to Run
--
-- * Run the pipeline. It should take a few seconds to populate input tables
-- from the Delta Lake and evaluate all views.
-- * Run the ad-hoc query to display the contents of the q1 view: `SELECT * FROM q1`
-- * To demonstrate incremental computation, insert a new record using the
-- following ad-hoc query:
-- ```
-- INSERT INTO LINEITEM VALUES (1, 5, 4, 1, 50, 0.80, 0.65, 0.10, 'B', 'C', '1998-09-01', '1998-09-01', '1998-09-01', 'DELIVER IN PERSON', 'TRUCK', 'new record insertion')
-- ```
-- * Re-run the `SELECT` query to see the updated results.
