----------------------------------
Summary: Get row information on DataWritableWriter once for better
writing performance
Key: HIVE-11131
URL: https://issues.apache.org/jira/browse/HIVE-11131
Project: Hive
Issue Type: Sub-task
Affects Versions: 1.2.0
Reporter: Sergio Peña
Assignee: Sergio Peña
DataWritableWriter is a class used to write Hive records to Parquet files. This
class is getting all the information about how to parse a record, such as
schema and object inspector, every time a record is written (or write() is
called).
We can make this class perform better by initializing some writers per data
type once, and saving all object inspectors on each writer.
The class expects that the next records written will have the same object
inspectors and schema, so there is no need to have conditions for that. When a
new schema is written, DataWritableWriter is created again by Parquet.
