Andy Grove created ARROW-9552:
---------------------------------
Summary: [Rust] [DataFusion] Implement metrics framework
Key: ARROW-9552
URL: https://issues.apache.org/jira/browse/ARROW-9552
Project: Apache Arrow
Issue Type: Improvement
Components: Rust, Rust - DataFusion
Reporter: Andy Grove
It is important for users to be able to debug query performance and each
operator is capable of collecting important metrics, like # of input and output
batches and rows, as well as elapsed time spent doing different types of
processing.
We should design traits for metrics reporting so that other projects using
DataFusion can access these metrics and make them available for users to see.
