Modern systems are usually designed as a collection of cooperating micro-services. These services commonly have their dedicated data stores for their individual needs. To support various requirements corresponding data are often stored in data stores with very different characteristics and use cases. A fundamental requirement emerging from these architectures is the need to reliably capture primary data changes. Change Data Capture (CDC) is a set of software design patterns used to determine and track the data that has changed so that action can be taken using the changed data. In this talk, I’d like to discuss the advantages and disadvantages of various CDC approaches, provide you guidance in this area and also share our experience including various samples, and recommendations.
