deemoliu opened a new pull request, #9665:
URL: https://github.com/apache/pinot/pull/9665
Add max and min partial upsert pre-defined mergers. They can be used for the
following use case.
`feature` `enhancement`
```
existing doc (offered_earliest_time = 10:00:00, offered_latest_time =
10:03:00)
new doc (offered.time = 10:05:00)
-> expected new doc (offered_earliest_time = 10:00:00, offered_latest_time =
10:05:00)
```
We can enable these mergers in the upsert Config as follows
```
{
"upsertConfig": {
"mode": "PARTIAL",
"partialUpsertStrategies":{
"offered_earliest_time": "MIN",
"offered_latest_time": "MAX"
}
}
}
```
