Just to think about this problem. I think we need to pre-define the granularity of segment metadata, then in the broker routing strategy, we can implement the hierarchy of segments with different time granularity. Then for each query, we can parse the time range from the query then pick the right segments to cover the entire time range. Also, have you tried Star-tree for this metrics aggregation use case? Though this is single-segment level aggregation. https://docs.pinot.apache.org/basics/indexing/star-tree-index ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
