Change Data Capture with Elixir and Debezium - ElixirConf EU23

Explore change data capture techniques using Elixir and Debezium in this ElixirConf EU23 conference talk. Dive into strategies for managing technical debt, building new models, and implementing the strangler fig pattern. Learn about sharing state, message brokers, and the intricacies of transactional logs and logical replication. Examine Debezium examples, comparing snapshot and streaming data capture methods. Investigate polymorphism, behaviors, schemas, and protocols in the context of change data capture. Address common concerns such as distributed message brokers, stable messages, and transactions. Discuss challenges including partitioning and consistency guarantees. Discover advanced solutions and consider when change data capture might be necessary for your projects. Conclude with insights from Greg Young and a Q&A session.
