Evolution of ETL-tools by the example of a single Big Data

Speakers will talk about how custom approaches to organizing and implementing ETL processes have changed, and how tools have changed following them to better respond to changing requirements and conditions. One of the interesting parts of the talk is a story about how the team began to abandon the use of non-standard native Hadoop tools in favor of the more standard Spark, what drove this and what results it led to. 

The talk will be of interest to data engineers, ETL specialists, data scientist, and anyone who wants to broaden their horizons or learn about the experiences of others.
