glasser commented on issue #9463: Add namespaces to Druid segments within a data source URL: https://github.com/apache/druid/issues/9463#issuecomment-598380163 It seems like an interesting application of namespaces is that it allows you to do reingestion and retention policies on a subset of a data source. For example, you could have a data source that contains customer data from customers in several pricing tiers. Querying should work the same for all customers, but you may want to load more history from customers who pay more (either in the "setting historical load rules" sense or the "actually killing old segments" sense), or you may want to run native batch reingestion on cheaper customers to reduce queryGranularity of their older data without needing to also rewrite the data from the higher tier customers. (Moving a customer between tiers in this model could still be a challenge, though, unless you can create a batch ingestion job that writes to a couple namespaces.)
