ETL vs ELT for ClickHouse

ETL

Previously, the ETL (Extract-Transform-Load) approach was used to load data to a data warehouse. The data were extracted from data sources, transformed to suit better for data analytics queries, and then loaded to a data warehouse. But with the advent of Cloud Data Warehousing (such as ClickHouse), the transformation process is more commonly performed at the data warehouse.

ELT (Replication)

ClickHouse provides affordable and nearly unlimited computing power which allows loading data to ClickHouse as-is, without pre-aggregation, and processing and transforming all the data quickly when executing analytics queries. Thus, the ETL approach transforms to ELT (Extract-Load-Transform). This may simplify data loading to ClickHouse greatly, as you don't need to think about the necessary transformations.
