Apache Pinot

what’s difference between `segmentUriPush` and `segmentMetadataPush`  ?

<https://docs.pinot.apache.org/basics/data-import/batch-ingestion#segment-push-job-type>

another question:
Example i has a offline table config like this
``` "segmentPartitionConfig": {
      "columnPartitionMap": {
        "campaign_id": {
          "functionName": "Modulo",
          "numPartitions": 2
        }
      }
    }```
And the ingest job in spark cluster.
So i must build the partition on spark job also, or i dont need pre partition on spark-job ?

Your source files must be partitioned by defined configuration in your table config. For example;

raw data (s3) =&gt; spark job(analyze data, and partition by campaign_id) =&gt; analyzed and partitioned data(s3) =&gt; pinot-spark-batch-ingestion-job =&gt; segments(s3)
