Version 2.9.0 v2
Enhancements, bug fixes, and other changes in MySQL Foreign Data Wrapper 2.9.0 include:
| Type | Description |
|---|---|
| Feature | Add a configuration file approach to control the pushdowns. We can now provide the list of operators and functions to be pushed down to the remote server safely. |
| Feature | Add support for the import_generated option in IMPORT FOREIGN SCHEMA to include columns generated from expressions in the definitions of foreign tables imported from a foreign server. |
| Feature | Add support for the TRUNCATE command to truncate foreign tables. |
| Feature | Add support for ON CONFLICT DO NOTHING in INSERT. It is mapping to INSERT IGNORE. |
| Feature | Add support for IS [ NOT ] DISTINCT FROM operator. |
| Bug Fix | Fix an oversight in assessing the pushdown ORDER BY clause. Don't push when underneath query_pathkeys is not safe to push down. |
| Bug Fix | Fix unstable ordering in the SQL/select test. |
| Bug Fix | Push down the LIMIT n clause when OFFSET is NULL. |
