It's exciting to see Neo4j Streams graduate from being a plugin to becoming a de-coupled bi-directional component that works with Aura!
In the blog article above a polling interval is selected for the frequency of data pulls from the source--Neo4j. But polling means that I may miss intermediate changes between two polls. I would like to have no polling and to instead have a log-based change data capture that will happen absolutely everytime the monitored entity changes, and only when it changes, whether it is 3 times per second or per week.
My question is: Does the new Kafka Connect Source support this? If not is there a non-Kafka Connect Source approach?
I am able to create something with triggers but I fear that too many triggers will place undue burden on the DBMS.
The meaning of 'log-based' is described well in the following text:
If you want to go “the whole hog” with integrating your database with Kafka, then log-based Change-Data-Capture (CDC) is the route to go. Done properly, CDC basically enables you to stream every single event from a database into Kafka. Broadly put, relational databases use a transaction log (also called a binlog or redo log depending on DB flavour), to which every event in the database is written. Update a row, insert a row, delete a row – it all goes to the database’s transaction log. CDC tools generally work by utilising this transaction log...
