>
> In connect-offsets topic:
> the offsets wrote by connector, key is
> `\{"cluster":"A","partition":2,"topic":"topic"}`
> after alter offsets, the key is
> `\{"partition":2,"topic":"topic","cluster":"A"}`
> !image-2024-04-25-21-28-37-375.png!
> in Worker.globalOffsetBackingStore.data, both two keys exist, because the are
> different strings:
> {"cluster":"A","partition":2,"topic":"topic"} {"offset":2}
>
> {"partition":2,"topic":"topic","cluster":"A"}{"offset":3}
> So alter offsets is not succussful, because when get offsets from
> globalOffsetBackingStore, always returns
> {"offset":2}
