> FLINK-25557  only resolves part of the problems. 
> Eventually, we should answer questions:
>  * How much Data Size increases/exploding
>  * When a checkpoint includes a new Materialization
>  * Materialization size
>  * changelog sizes from the last complete checkpoint (that can roughly infer restore time)
