  he explains ~40y ago invented data warehouse, where an ETL process overnight would collect data from smaller dbs into a central db (the data warehouse) ~15y ago, data lake (i.e. hadoop) emerged to address scaling and other things. Same idea but ELT instead of ETL: less focus on schema, collect the data into S3 and transform it later
