yanghua commented on issue #1440: [HUDI-731] Add ChainedTransformer

@xushiyan 's explanation is correct. It's just about trade-off. Both of
them can achieve the same function, but the mechanism of collecting
`Transformer` is different. Considering that we have limited the functionality
of this `Transformer` to: `ChainedTransformer`. Maybe we can hide the
"collect/assemble" logic to users? From this perspective, perhaps
@vinothchandar 's suggestion is a little better for users.
After all, in terms of flexibility, if users want more flexibility, they can
even directly inherit the `Transformer` interface and implement everything you
currently implement, right?
