> Currently, Flink CDC allows three SE strategy: evolving it, ignoring it, or
> throwing an exception. However such configuration strategy doesn't cover all
> user cases and requires want more fine-grained strategy configuration.
> This ticket suggests adding one more strategy "try_evolve" or
> "evolve_when_available". It's basically like "evolving" option, but doesn't
> throw an exception if such operation fails, which provides more flexibility.
> Also, this ticket suggests allowing user to configure per-schema-event
> strategy, so users could evolve some types of event (like rename column) and
> reject some dangerous events (like truncate table, remove column).
