Lookup integration test

Created using Ubuntu WSL. Other Linux flavors and MacOS may require edits.

lookup_quicktest vs lookup_bigtest

This test comes in two flavors.

portfolio_quicktest has all data ready, it just has to be copied to /tmp/capi_*, and you can run the test. Root-level copy_demo_data.sh script does that, among other things.

lookup_bigtest is a variation of this test that uses:

• large number of orders
• parquet files for input and output and requires test data to be generated - see 1_create_test.data.sh.

Workflow

The DOT diagram generated with

go run capitoolbelt.go validate_script -script_file=../../../test/data/cfg/lookup_quicktest/script.json -params_file=../../../test/data/cfg/lookup_quicktest/script_params_two_runs.json -idx_dag=true

and rendered in https://dreampuf.github.io/GraphvizOnline :

What's tested:

• table_lookup_table with parallelism (10 batches), all suported types of joins (inner and left outer, grouped and not)
• file_table read from single file
• table_file with top/limit/order
• single-run (test_one_run.sh) and multi-run (test_two_runs.sh) script execution

Multi-run test simulates the scenario when an operator validates loaded order and order item data before proceeding with joining orders with order items.

How to test

See integration tests section for generic instructions on how to run integration tests.

Possible edits

Play with number of total line items (see "-items=..." in 1_create_data.sh).
