@peferron I don't see why a local cache is needed on historicals in this setting, apart from the short period of time between the end of the execution on the historical and the moment of the population in memcached. But it seems to me that this should properly be handled by a [small "admission" cache](https://github.com/apache/incubator-druid/issues/7186), which is write-through by design, so there is no problem that you've described.
