I have a study on ETL tools and recently heard a lot of voice on just need to do ETL programming using script/coding, e.g. R and Qview, so is this means now ETL tools like MS SSIS is useless ?
what is the pros and cons on doing ETL logic by coding and ETL tools?
it seems now doing ETL code in container level with RESTFUL API already make ETL process can do load balancing, parallel execution and scale out (by container), is that correct ? so no need ETL tools any more ???
the new MariaDB X3 platform seems can even ignore ETL process as it can stream data directly form OLTP to OLAP, so not need ETL anymore?
