-------------------------------------
Summary: Push projections and filters to S3 as S3Select queries
Key: HIVE-21112
URL: https://issues.apache.org/jira/browse/HIVE-21112
Project: Hive
Issue Type: Improvement
Components: Hive
Reporter: Miklos Gergely
Assignee: Miklos Gergely
S3 Select enables applications to retrieve only a subset of data from an object
by using simple SQL expressions.
S3A connector for Hadoop adds an API that aims at supporting S3 select queries.
This issue initiates the work needed on the Hive side to create the S3 queries
from the projection and filter expressions pushed to TS operators.
