设置当前会话（Session）的DML是否在日志节点（Change Data Capture,CDC）生成Binlog

sql_log_bin变量可以控制当前会话（Session）的DML在日志节点（Change Data Capture，CDC）是否会生成Binlog，默认情况下允许生成Binlog。批量更新或插入数据时会大量生成Binlog，会对Binlog生成和下游消费端的性能产生较大影响。若实际业务中不需要CDC产生的DML Binlog，可以通过sql_log_bin关闭生成Binlog。

Flink CDC有办法自定义同步到 Sr 的数据库名称吗？

Flink CDC无法创建带减号➖连字符的数据库名， mysql的库名又是这种格式，所以有办法自定义同步到 Sr 的数据库名称吗？

Flink CDC有没有办法可以做到cdc表更新以后就去数据库查询最新的jdbc表呢？

Flink CDC中flinksql进行一个3张表的全量加增量实时联表同步，现在我如果3张表都用cdc连接器，flink程序的内存就会涨的很快，如果设置状态过期时间，就会导致数据丢失，因为不同表的时间跨度可能会比较长现在，我把这三张表更新最迟的一个表使用cdc连接器，其余两个使用jdbc连接器，但是flink会缓存jdbc的表，所以联表执行的不是数据库的最新数据，有没有办法可以做到cdc表更新....
