My comment was a bit ambiguous. So, for sheets where we have to load all data, we would load all columns at once as a parquet file. (I will leave comment for the advantage of this approach in the next comment) On the other hand, let’s say we have to draw a chart from a column. The type chart could be changed by user - they could be Pie charts, means, time series chart, median, table or even dot products. To achieve this goal, we would bring just a column from s3 using duckdb, and apply sql queries from client side, rendering adequate ui. |
