-------------------------------------
Summary: Cannot stream Dates to Parquet
Key: ARROW-15236
URL: https://issues.apache.org/jira/browse/ARROW-15236
Project: Apache Arrow
Issue Type: Bug
Components: C++
Affects Versions: 6.0.1
Reporter: Caleb Epstein
Attachments: parquet.cpp
I cannot for the life of me figure out how to write a DATE to a Parquet file
using the parquet::StreamWriter API. See attached example code, which
generates this exception when writing the second column:
{code:java}
❯ ./parquet
terminate called after throwing an instance of 'parquet::ParquetException'
what(): Column converted type mismatch. Column 'date' has converted
type[DATE] not 'INT_32'
{code}
I have also tried:
* Declaring the field's type as `INT64`, which yields the exception {{DATE can
only annotate INT32}} when defining the schema.
* Declaring the field using the alternate version of {{Make}} with
{{LogicalType::Date(), Type::INT32}}. This yields the same exception as the
code attached.
