Hi @npawar , I have tried to do the same in existing table, but existing
table is not showing any value:
"ingestionConfig": { "transformConfigs": [ { "columnName": "header.trId",
"transformFunction": "JSONPATHSTRING(header, '$.trId')" } ] }, created new
column as header_trId in existing schema and table, but for new messages
header_trId is always coming as null. I reloaded the segments also but no luck.
Tried same table config and created new table and it worked, is it not gonna
work with existing table, if this the case how we will update or add schema if
need to add new fields to the schema. Please suggest am I missing any steps in
between.
