Ada Wong updated FLINK-25485: ----------------------------- Description: When we directly use buffer-flush options of the mysql sink (sink.buffer-flush.max-rows and sink.buffer-flush.interval) can not increase throughput. We must set 'rewriteBatchedStatements=true' into mysql jdbc url, for 'sink.buffer-flush' to take effect. Such as: jdbc:mysql://ip:3306/dbname?rewriteBatchedStatements=true I want add a method appendUrlSuffix in MySQLDialect to auto set this jdbc option. Many users forget or don't know this option.
