I have been working in the data warehousing / business intelligence field for the last 25 years. I have probably been exposed to every traditional technology under the sun. I am honestly having a really hard time understanding what the big deal is with the whole data lake / Serverless X / spark / airflow / metric store / etc. It seems to me that these technologies are geared towards use cases that either involve data volumes that most companies will never reach or reinvent stuff that already exists (how is a metric store any different than an OLAP cube with calculations?) What is it that’s so great that’s not solved by a file system, traditional ETL and a RDBMS?</P> Mon, 01 May 2023 10:33:13 GMT rekhaben92 2023-05-01T10:33:13Z https://community.qlik.com/t5/Catalog-and-Lineage/What-problems-does-the-modern-data-stack-actually-solve-that/m-p/2066291#M961 <P>Help an old guy out here!
