I asked this question on Reddit a while back and received lots of valuable answers.
Therefore, I’ve looked into each answer and documented the results in this article.
TL;DR
No, Debezium dominates the market at the moment, despite some drawbacks.
Background Explanation
Why would we want to find an alternative to Debezium? The main reason is we encountered a challenging scenario.
This is a typical scenario for Debezium, where any modifications to the data source are captured and fed into Kafka for downstream processing.
The advantage of this architecture is simple and efficient, ensuring all downstream processes are as real-time as possible.
If the source has a large number of updates, Debezium can scale horizontally until a large number of updates are concentrated in a single table. This is where Debezium hits its limits.
