Thanks Pavel. Is this feature available in Ignite .NET ? Can you share the sample example?

This is needed for resiliency test for Ignite cluster where we shutdown one cluster and move all application service to backup cluster as part of resiliency testing. Basically need to know which Ignite features supports to capture changes in caches so that we can write programs to capture those changes and stream those to Kafka using .NET libraries. Found this doc but not sure how Ignite .NET fits into this ( CDC replication using Kafka) https://ignite.apache.org/docs/latest/extensions-and-integrations/change-data-capture-extensions<https://clicktime.symantec.com/15t5ekZ4xyfdJnUvx3tRB?h=uLyfAFvoWOjEF9JvWuSOSIGaUYLH7IKGUW28dcFAg2M=&u=https://ignite.apache.org/docs/latest/extensions-and-integrations/change-data-capture-extensions> Can you share some working examples to capture the changes happening to cache realtime using .NET?
