I figured it out finally. I set **"stream.kafka.metadata.populate": true**
configuration in **tableIndexConfig.streamConfigs** and
> {
"name": "__metadata$offset",
"dataType": "STRING"
},
{
"name": "__header$channel",
"dataType": "BYTES"
},
{
"name": "channel",
"dataType": "STRING"
}
added these column definitions into **dimensionFieldSpecs**. Header values
are in BYTES type so I converted them to STRING via this code in
**ingestionConfig.transformConfigs**
> {
"columnName": "channel",
"transformFunction": "fromUtf8(__header$channel)"
}
So, **channel** column is visible in Pinot table.
