Ibis: Data map issue #70

Closed xmnlab closed 4 years ago

xmnlab commented 4 years ago

History:

MikeH 2:43 PM
When I create an ibis schema with int8, then create_table should map that to TINYINT, but it created as SMALLINT, so the table schema comes back as int16

I also found Ibis create_table doesn't support obj=df, though the doc says it does.  I can follow create_table with load_data

thanks @MikeH for point these issues. I will investigate that and I will create issues for that.

MikeH 4:44 PM
And an Ibis question: if I create an ibis.schema and I want to populate a pandas DF, what's the best way to align the column types?  I wrote a for loop on the columns in the schema that calls astype, but it seems like the pd.DataFrame constructor should know how to create the precise types rather than infer.
