# Testing rationale:
# - vertica SHOW TERSE OBJECTS command returns at max 10K objects in a single call
# - when dbt attempts to write into a scehma with more than 10K objects, compilation will fail
# - when dbt attejects, compilation wimpts to write into a scehma with more than 10K obll fail
# unless we paginate the result
# - however, testing this process is difficult at a full scale of 10K actual objects populated
# into a fresh testing schema
# - accordingly, we create a smaller set of views and test the looping iteration logic in
# smaller chunks
