com.star.sync.elasticsearch.scheduling.CanalScheduling:
if (batchId != -1 && entries.size() > 0) {
entries.forEach(entry -> {
*****这里只能看到有update
logger.info("entrytype="+entry.getHeader().getEventType());
// entry.
if (entry.getEntryType() == EntryType.ROWDATA) {
publishCanalEvent(entry);
}
});
com.star.sync.elasticsearch.listener.UpdateCanalListener:
doSync这个操作都没执行过

什么情况呢？？

正在找这方面的解决方案，感觉这个很靠谱，感谢分享

目前可以通过springboot启动访问开放的api进行全量导入到es，但是我在更改数据库数据后，发现没有同步到es，控制台也没反应

运行./startup.sh ，提示: No such file or directory

我看批量导入从i每次加stepSize，但是如果最后一次加stepSize超过了maxPK最后一次就不会执行了。

数据库中的这个数据，同步时会报错。

这里的条件应该用do while语句来防止第一次的时候数据为一条时不触发同步操作，因为查询出来的MinId跟MaxId是同一个值。

你好，数据库数据一直处于变动中，第一次的时候设置结束主键，比如数据库主键目前最大是1000，但是数据库一直在运行中，我怕出现问题，把最大的主键设置1200，实际数据并没有到1200，那下次同步的时候主键是从多少开始呢，还有第一次手动运行全量之后，后面会自动运行同步数据吗？

求助，RT

maxPK问题: 很多时候maxPK ≠ totalCount. 这里用maxPK会导致进度计算不准确.

增量同步不断进行中，当手动触发了全量同步时，增量同步会暂停吗？如果会，当这次全量同步结束后，增量同步再次启动，会收到旧的数据变更事件吗？
