Never mind about my original question, it does use

druid.worker.category

holy cow, the new indexer is 33% faster and consumes way less memory. But I am confused about the server breakdown. I see: • type:

indexer

, tier:

_default_tier

. This is the thing that performs ingestion. • type:

peon

, tier:

my-custom-category

. What does this do? What is the relationship between

peon

and

indexer

?
