[GitHub] [incubator-pinot] deemoliu opened a new issue #6575: implement partial upsert support on Pinot
deemoliu opened a new issue #6575:
URL: https://github.com/apache/incubator-pinot/issues/6575
With the foundation of full upsert support (#4261) in Pinot, another category of use cases on partial upsert can be enabled. Partial upsert is convenient to users so that they only need to specify the columns whose value changes, and ignore the others. For example, the ride fare can be adjusted by adding another $5. With partial upsert, developers can specify the incremental amount only, instead of looking up the previous value and merging the change. Manually doing this can be both complicated and inefficient. In order to extend the functionality of Pinot and serve more use cases, we are going to implement the partial upsert features in Pinot which allow users to operate updates on specified columns.
Few Challenges that we want to solve.
1. Different merge strategies.
2. Nonexisting record handling.
