A tale about how we build DWH: From MySQL replicas to Exasol + ClickHouse

In this talk, Ekaterina wants to talk about why Citymobil chose Exasol as the DBMS for the warehouse, and Data Vault as the data model. But didn't abandon the Data Lake concept completely.

Attention will be paid to how data flows are now arranged: the company has developed its own flexible and scalable ELT mechanism so as not to get used to the limitations of box solutions.

We'll also look into the bright future: the speaker will talk about plans for the implementation of Self Service ETL and how the company wants to allow users to create their data storage and quality checks.
