BLOB field slows down when JDBC sink is written

Open ryan-0526 opened this issue 2 years ago • 0 comments

Hello, I use Kafka connect JDBC sink to write data to Oracle. Once the BLOB field type is added, it becomes very slow. For example, I define the writing batch size as 20000. Adding the BLOB field, it takes 3 hours to write about 3.5 million data. If the BLOB field is not added, the same batch will be written in less than 10 minutes
