steps to reconstruct:
- create redshift cluster
- create new external schema called spectrum and reference to the original schema used in Athena: e.g tpch_data. notice XXXXX should be your account number.
- query your data , using the new schema name.
create external schema spectrum
from data catalog
create external database if not exists;
select count(*) from tpch_data.lineitem_parquet; — will not work
select count(*) from spectrum.lineitem_parquet; — will work.
