yuzhou updated KAFKA-16621:
---------------------------
Description:
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}
