Apache Pinot

:question:Looks like _partition-based segment pruning_ in Pinot can be configured for _multiple columns_ for `offline` tables.
Appreciate any help in confirming if the same applies to `real-time` tables as well :woman-bowing: Here is the associated reference for Kafka stream, but it doesn't explicitly mention if partition-based segment pruning can be set up for multiple columns in the corresponding Pinot table config: <https://docs.pinot.apache.org/basics/getting-started/frequent-questions/ingestion-faq#how-do-i-enable-partitioning-in-pinot-when-using-kafka-stream>

I guess the pre-requisite is: Input Kafka stream needs to be configured with a custom partitioner to match the partition column(s), partition function and number of partitions set up in the Pinot table config.

Yea, for RT upstream will need to take care of that 

Do we have to setup something like below in the RT table config involving >1 column?
```"tableIndexConfig": {
      ..
      "segmentPartitionConfig": {
        "columnPartitionMap": {
          "memberId": {
            "functionName": "Modulo",
            "numPartitions": 3 
          },
          "caseNumber": {
            "functionName": "Murmur",
            "numPartitions": 12 
          }
        }
      }```
