Tank you sir, very helpful. Could you also briefly describe from your
experience the major differences between traditional ETL in DW and ELT in
Hive? Why there is emphasis to take data from traditional transactional
databases into Hive table with the same format and do the transform in Hive
Traditionally data in Hive was write once (insert) read many. You could
append to tables and partitions, add new partitions, etc. You could
remove data by dropping tables or partitions. But there was no updates
of data or deletes of particular rows. This was what was meant by
immutable. Hi
