I configure canal HA , how to configure the syncClinet ? or not support ?
从CanlClient是异步的获取的数据 然后消费的吗?
比较菜没看懂, 就看到kafka.target_deep=4的意思 ,请问还有几个值呢?分别是什么作用?
当一个批次的数据其中一条或几条数据发送失败,导致ret=false,然后程序继续处理这个批次后面的数据,这个时候,如果后面的数据(数据A)发送到kafka成功,到这个批次处理结束后,ret仍然是false吧,然后就回滚了,回滚后,继续按之前的位点消费,是不是导致发到kafka的数据(数据A)重复了?
canal同步数据到ES时,如何设置ES到用户名和密码?
目前是每个表一个topic,表很多的时候消费起来不方便.
将mysql准实时订阅到kafka,保证数据不丢失。
请问在kafka producer发送到kafka ack=all的情况下,大概发送消息的吞吐量是多少?
