------------------------------------
Summary: Fix cursors to do "do-at-open" semantics
Key: SPARK-55451
URL: https://issues.apache.org/jira/browse/SPARK-55451
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 4.2.0
Reporter: Serge Rielau
The curent implementation of cursors only starts executing on first fetch.
That means that table changes AFTER OPEN are still visible.
That's wrong.
Ideally we would like freeze the snapshot at OPEN and start executing on first
FETCH, but that is difficult. Semantically sane is to start executing at OPEN.
