----------------------------------
Summary: Refactor Parquet Record Reader
Key: DRILL-5356
URL: https://issues.apache.org/jira/browse/DRILL-5356
Project: Apache Drill
Issue Type: Improvement
Affects Versions: 1.10.0, 1.11.0
Reporter: Paul Rogers
Assignee: Paul Rogers
Priority: Minor
Fix For: 1.11.0
The Parquet record reader class is a key part of Drill that has evolved over
time to become somewhat hard to follow.
A number of us are working on Parquet-related tasks and find we have to spend
an uncomfortable amount of time trying to understand the code. In particular,
this writer needs to figure out how to convince the reader to provide
higher-density record batches.
Rather than continue to decypher the complex code multiple times, this ticket
requests to refactor the code to make it functionally identical, but
structurally cleaner. The result will be faster time to value when working with
this code.
This is a lower-priority change and will be coordinated with others working on
this code base.
