Ideas for Event Sourcing in Oracle

Log Miner or are there other alternatives?

With microservices, the architects want to dismantle the monolithic database and replicate data rather than share it. Then raises the need to audit the changes where the modifications are done (like the C in CQRS). The Oracle database already does that for recovery purpose, building the redo records before modifying the data blocks, but that’s a physical change vector. We need something logical with more possibilities to filter and transform. There are multiple possible methods for this. But unfortunately, the ones that were built in the database are slowly removed since Oracle has acquired Golden GAte and sells it separately.
