[GitHub] [incubator-pinot] MrNeocore opened a new issue #7077: Backward compatible change leading to non-queryable REALTIME table ?

MrNeocore opened a new issue #7077:
URL: https://github.com/apache/incubator-pinot/issues/7077


   Following Slack discussion: https://apache-pinot.slack.com/archives/C011C9JHN7R/p1624260346227200
   
   After adding a new INT column on a REALTIME table via updating its schema file and calling the CLI `AddTable` command - the schema is correctly updated but querying the table results in the following error :
   
   ```
   [
     {
       "errorCode": 500,
       "message": "MergeResponseError:\nData schema mismatch between merged block: 
   [communityId(STRING),documentId(STRING),eventTimeString(STRING),eventType(STRING),hoverDuration(INT),ibcustomer(STRING),origin(STRING),projectId(STRING),selectionId(STRING),timeString(STRING),userId(STRING)] 
   and block to merge: 
   [communityId(STRING),documentId(STRING),eventTimeString(STRING),eventType(STRING),ibcustomer(STRING),origin(STRING),projectId(STRING),selectionId(STRING),timeString(STRING),userId(STRING)], 
   drop block to merge"
     }
   ]
   ```
   
   _Additional context:_
   - Column was first added as Dimension, then changed to Metric
   - The newly added field come from a JSON sub document, and is parsed via `ingestionConfig.transformConfig` with defaut value (-1).
   
   @xiangfu0 Suggested to restart the REALTIME servers - but any non "operational" and downtime-less solutions would be ideal if possible :)

   This behavior is due to the fact that `pinot.server.instance.reload.consumingSegment` was off (`false`)
   The following PR https://github.com/apache/incubator-pinot/pull/7078/files updated this default behavior :+1: 
   
   Closing !
