Debezium reads MySQL binary logs and PostgreSQL WAL to stream every row-level change as a Kafka event in near real-time — replacing nightly batch ETL with sub-second data propagation.

PostgreSQL views historically executed with the owner's privileges, bypassing row-level security policies. PostgreSQL 15 fixed this with security_invoker views — here's why it matters and how to use it in multi-tenant schemas.
