QP Hou created ARROW-8744: ----------------------------- Summary: [Rust] ParquetIterator's next method should be safe to call even after reached end of iteration Key: ARROW-8744 URL: https://issues.apache.org/jira/browse/ARROW-8744 Project: Apache Arrow Issue Type: Improvement Reporter: QP Hou Assignee: QP Hou
Once reached end of iteration, calling next on ParquetIterator will result in an error. This is inconvenient in two ways: * when shared between multiple threads, only one of the thread will be able to terminate without error * sender for response_rx cannot terminate the iteration early and free up resources, instead, it needs to always wait for signal from request_tx before closing up the connection -- This message was sent by Atlassian Jira (v8.3.4#803005)
