Summary: Support Reading and Writing Puffin File Stats for Iceberg
Tables
Key: IMPALA-13041
URL: https://issues.apache.org/jira/browse/IMPALA-13041
Project: IMPALA
Issue Type: Improvement
Components: Backend, Frontend
Reporter: Manish Maheshwari
Puffin File format is an iceberg upstream spec to support stats for iceberg
tables. These stats cannot be both read and used for query planning and written
by Impala today. We want to extend support in Impala to do the below -
# Read stats from Puffin files
# Write stats to puffin files during load/insert/update/delete commands (as
applicable)
# Modify compute stats command for iceberg tables to compute stats and store
them in Puffin files
