Summary: Support Bucketed Table And Related Optimizations
Key: IMPALA-11600
URL: https://issues.apache.org/jira/browse/IMPALA-11600
Project: IMPALA
Issue Type: New Feature
Components: Backend, Distributed Exec, Frontend
Reporter: Baike Xia
In Hive, we can create bucket tables, divide data in fine-grained ways, and
publish data to different files based on bucket columns. Like this, we can make
specific optimizations to the Query to speed up the Query.
I think it would be exciting for Impala to have support for bucket table
creation and related optimizations.
The following document is a design document that supports the creation of
bucket tables. If you are interested, welcome to give some suggestions.
