Initially, without creating static looup In coordinator log, we could see below messages after every 2 mins 2023-01-17T043923,100 INFO [LookupCoordinatorManager--0] org.apache.druid.server.lookup.cache.LookupCoordinatorManager - Not updating lookups because no data exists 2023-01-17T044123,100 INFO [LookupCoordinatorManager--0] org.apache.druid.server.lookup.cache.LookupCoordinatorManager - Not updating lookups because no data exists But once the lookup is created, I could see the lookup not found exception error if we open the lookup immediately { "type": "map", "map": { "a": "alpha", "b": "beta" } } After some time, we could see the values. I don’t see the ‘ Not updating lookups because no data exists‘ log being logged anymore but nothing related lookup is getting logged after that. One more thing is if I update anything in the lookup , there is nothing being logged in the coordinator or broker or router related to it though the lookup get updated
