Why make bql long format?

[postelrich]

bdh and bdp return data in wide format. Why does bql standalone in taking the data which is long format and convert it to long format? Multiple query responses?

How can I make bquery.bql(expression) return a list of dataframes, instead of one dataframe?

[postelrich]

Thats my question, is it long format because multiple queries can be made in one call?
