I have lot of tables with 80% of columns being filled with nulls. I understand SQL sever provides a way to handle these kind of data during the data definition of the tables (with Sparse keyword). Do datalake provide similar kind of thing?
Unless you compress the entire CSV, which also should be a viable approach.
That said, Delta/Parquet would normally be the better option where each column in compressed.
