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.
