Hi, you can use BulkSql, a built-in feature of Oracle .net driver and implemented in Dapper.Oracle.
Please see https://github.com/DIPSAS/Dapper.Oracle/blob/master/doc/BulkSql.md for details.
I've tested this approach with 2000+ records at once, but for 35.000 you might want do do it in separate operations.
Let me know if you have any further questions!
