----------------------------
Summary: Re-implementation for some data types of Parquet in HAWQ
Key: HAWQ-831
URL: https://issues.apache.org/jira/browse/HAWQ-831
Project: Apache HAWQ
Issue Type: Task
Components: Storage
Reporter: Lili Ma
Assignee: Lei Chang
Re-implement some HAWQ data type mapping to Parquet, so that HAWQ can be
compatible with Hive.
1. Currently HAWQ converts data type decimal to byte array, we can modify it to
fixed length byte array, so that HAWQ can be compatible with Hive.
2. HAWQ itself can convert the data type char to int32 instead of byte array,
so that the space for char storage can be saved.
3. To be compatible with Hive, HAWQ can change its type mapping for decimal to
int96, but this need discussion.
