> Not sure if this is a duplicate, but as this issue pops up over and over
> again, it might be time to discuss it here and fix it.
> Currently, configuration is spread across instances of {{Configuration}} and
> POJOs (e.g. {{ExecutionConfig}} or {{CheckpointConfig}}). This makes it very
> tricky to handle configuration throughout the stack. The practice has shown
> that configuration might be passed, layered, merged, restricted, copied,
> filtered, etc. This is easy with the config option stack but very tricky with
> the existing POJOs. Esp. it is difficult to keep the two in sync or compare
> them.
> Many locations reveal the current shortcoming. For example,
> {{org.apache.flink.table.planner.delegation.DefaultExecutor}} has a
> {{isCheckpointingEnabled()}} method simply because we cannot trust the
> {{Configuration}} object that is passed around. Same for checking if object
> reuse is enabled.
> A solution is still up for discussion. Ideally, we deprecate
> {{ExecutionConfig}} and {{CheckpointConfig}} and advocate a pure config
> option based approach. Alternatively, we could do a hybrid approach similar
> to `TableConfig` (that is backed by config options but has setters for
> convenience). The latter approach would cause less deprecations in the API.
