-------------------------------------
Summary: [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
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
