贴一下你写的代码哈。讨教一个问题
@Override
public void run() {
while (!threadPool.isShutdown() && !threadPool.isTerminated()) {
Message message = connector.getWithoutAck(canalConfig.getFetchSize(),10L,TimeUnit.SECONDS); // 获取指定数量的数据
long batchId = message.getId();
int size = message.getEntries().size();
if (batchId == -1 || size == 0) {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
logger.warn("CustomSimpleCanalClient invoke thread interrupted!");
}
} else {
List<Entry> entryList = message.getEntries();
for (Entry entry : entryList) {
try {
customTableQueue.put(entry);
} catch (InterruptedException e) {
//do nothing
logger.warn("customTableQueue interrupt.", e);
}
}
}
connector.ack(batchId); // 提交确认
}
}
如果你放到阻塞队列里面就ack了,那么 ack完后,突然宕机,是不是customTableQueue的entry都丢了,然后canal server的数据也被删除了?这是有问题的吧?
