--------------------------------------
Assignee: Phillip Cloud
> [C++] Read and write Arrow decimal values
> -----------------------------------------
>
> Key: PARQUET-1095
> URL: https://issues.apache.org/jira/browse/PARQUET-1095
> Project: Parquet
> Issue Type: New Feature
> Components: parquet-cpp
> Reporter: Wes McKinney
> Assignee: Phillip Cloud
> Fix For: cpp-1.4.0
>
>
> We now have 16-byte decimal values in Arrow which have been validated against
> the Java implementation. We need to be able to read and write these to
> Parquet format.
> To make these values readable by Impala or some other Parquet readers may
> require some work. It expects the storage size to match the decimal precision
> exactly. So in parquet-cpp we will need to write the correct non-zero bytes
> into a FIXED_LEN_BYTE_ARRAY of the appropriate size.
> We should validate this against Java Parquet implementations
