Hi, I've noticed this new Jira ticket:
https://hibernate.atlassian.net/browse/HHH-11260 and I think we should correlate the Session#stream and Session#scroll with database cursors. While Oracle uses a fetch size of 10, and SQL Server uses an adaptive cursor, PostgreSQL and MySQL just fetch the whole result set into the client. So, for MySQL we could do as suggested in the Jira ticket, by setting the fetch size to Integer.MIN_VALUE. My question is about PotgreSQL. Postgres requires setting the fetch size to some positive value in order to turn the current statement into a database cursor. Now, should we set a default value for streaming (e.g. 10), which can be controlled via a new config property: hibernate.jdbc.stream.fetch_size Let me know what you think.
