> Generally we provide both row and column based access despite being column store. So anything a traditional database does we can do too.

Does quest DB use the same physical data layout for the row based access? My understanding was providing an entire row of data from a columnar file is expensive because you have to assemble the row from num_columns different slices of the columnar file.




The data layout is indeed the same for both cases. We don't assemble row as such. In QuestDB row is a collection of data addresses, each of which is calculated lazily using row_id and bitshift
