Hi everyone,

 

I have a question about the state of decimal support in Arrow when reading
from/writing to Parquet.

*       Is writing decimals to parquet supposed to work? Are there any
examples on how to do this in C++?
*       When reading decimals in a parquet file with pyarrow and converting
the resulting table to a pandas dataframe, datatype in the cells is
"object". As a consequence, performance when doing analysis on this table is
suboptimal. Can I somehow directly get the decimals from the parquet file
into floats/doubles in a pandas dataframe?

 

Thanks in advance,

Roman
