what is recommended indexing rules for ETL in general?


Hello Experts,

What kind of indexes are recommended for staging area in ETL flow. For example unique index on natural key columns. I have surrogate key as well in data flowing in from source.

Also any suggestion/recommendation for indexing in other layers like dimensional data model layer and type 1 persistent data layer for full snapshot data.

Thanks, Rajneesh
