然后实时的数据集,其实我目前来说主要就是在DTS这一块,然后这个新的特性这个stream server呢,我觉得后面整个的升级之后可能对我们应用方是没有感知的,但是它整体带来的效果就是可能它的写入速度同比会更快,因为我们很多的实时的数据的写入都是在每天往这个数据仓库里面在写。 三、AI赋能业务的探索实践 1.当前数据架...

You can then use logical replication to continuously stream the newer data recorded after the LSN and synchronize the changes from publisher to subscriber. Specifically, it allows the customer to create a logical slot on a source RDS database, take a snapshot, restore the snapshot to a new ...
