I have been using druid-0.8.1-rc2
I have been batching files from Camus, and then using the delta ingestion to batch in new files.
It runs much faster. Nice!
So I have a question, what happens if you originally batch ingested files using one partitionSpec, say with “type” : “dimension” and then you later delta ingested with “type”:“hashed”.
What are the implications of changing the partitionSpec for part of the segment?
