Hi,

[/data/jenkins/workspace/RE-ReleaseBuilds/RE-Miner/server/udx/supported/ParquetExport/ParquetExport.cpp:1709], error code: 0, message: ERROR: Decimal type with precision 47 (> 38) is not supported

To work around, I need to find columns in table with unsupported datatypes, and instead of SELECT *, write list of table columns, and use to_char for columns with unsupported datatype.

Can you ask development team for a new feature, to support all unsupported types in Export To Parquet.

If Export To Parquet encounter unsupported datatype, use string field in Parquet, and convert Vertica column to string, using default conversion to_char.

Development can add parameter (something like we_love_our_users_and_we_will_convert_unsupported_datatypes_to_string, default False).

Thank you
Sergey
