https://community.cloudera.com/t5/Support-Questions/How-Atlas-is-notified-when-there-is-a-change-in-any-data/m-p/209628#M171582 <P>These are good questions. I hope I am able to do justice to them with my answers.</P><P>To elaborate little more on what <A rel="user" href="https://community.cloudera.com/users/12092/ssubramanian.html" nodeid="12092">@Sarath Subramanian</A> said. Kafka is used to do the work of relaying the notifications from Hive to Atlas. Hive publishes to a topic and Atlas subscribes to that and thus receives the notifications.</P><P>There has been some discussion on using Atlas for MySQL and Oracle. I have not seen any implementation yet. This is possible, provided these 2 products have notification mechanisms. From what I know, these have database change triggers that be used to call a REST API or push some message onto a queue or publish to Kafka.</P><P>For Oracle, <A href="https://docs.oracle.com/cd/B19306_01/B14251_01/adfns_dcn.htm">this</A> is what i found.</P><P>Hope this helps.</P> Fri, 16 Jun 2017 23:18:22 GMT amestry 2017-06-16T23:18:22Z
