[jira] [Created] (ARROW-11558) [C++] Push down projection and
selection to S3 Select
Ian Cook created ARROW-11558:
--------------------------------
Summary: [C++] Push down projection and selection to S3 Select
Key: ARROW-11558
URL: https://issues.apache.org/jira/browse/ARROW-11558
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Ian Cook
Amazon S3 Select [1], an S3 feature generally available since April 2018 [2], can improve S3 read performance by allowing S3 clients to use a limited subset of SQL to specify projection and selection [3] on data in some formats [4]. It would be interesting to try using this in Arrow and to measure its effects on S3 read performance under various conditions.
