I'm missing a more detailed description of column indexes. The documentation says "Columnar storage, in many cases, eliminates the need for additional index structures..." but no further details. In my case, I've got a column which contains Ascii strings which in other DBs is implemented as VARCHAR(200). Lookup on this column is made only by string equality, no substring search. Does it mean that in Hana, I can also model this column as VARCHAR(200) and need no index on this column? Or do I need one?
Cheers,
