--------------------------------------
Assignee: Serge Rielau
> 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
> Assignee: Serge Rielau
> Priority: Major
> Labels: pull-request-available
>
> 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.
