Partial Update with some partition column/key is not working as expected.
Let's suppose I am currently having following event/message.
{
"id": 1,
"language": "python",
"created": "2023-07-12",
"updated": "2023-07-12"
}
Here my,
primaryKey = id
deDupKey/preCombine Field = updated
partition Field = created.
& I am applying UPSERT as writeOperation type.
Now I want to apply the partial update when I am receiving record from my
source system/producer.
New incoming event is as following.
{
"id": 1,
"language": "scala",
"updated": "2023-07-13"
}
Now after partital update, I want to update only columns like `language` &
`updated` column. But after applying partital update, we are getting `null` in
CREATED column.
Expected Event after merge/partital update should be
{
"id": 1,
"language": "scala",
"created": "2023-07-12",
"updated": "2023-07-13"
}
but it coming as
{
"id": 1,
"language": "scala",
"created": null,
"updated": "2023-07-13"
}
Which is actually wrong. Will you please help us here? Are we doing
something wrong?
