[jira] [Updated] (ARROW-15236) Cannot stream DATE to Parquet
[ https://issues.apache.org/jira/browse/ARROW-15236?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Caleb Epstein updated ARROW-15236:
----------------------------------
Summary: Cannot stream DATE to Parquet (was: Cannot stream Dates to Parquet)
> Cannot stream DATE 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
> Priority: Minor
> 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.
