Is this what you are looking for: https://druid.apache.org/docs/latest/querying/lookups.html#update-lookup & https://druid.apache.org/docs/latest/querying/lookups.html#api-for-lookup-status I could not find a way to manually trigger the refresh of the lookup. But you can control the poll period of the JDBC lookup. By default it will load only once, but by setting the

pollPeriod

it will reload periodically. If you also specify the

tsColumn

is can do incremental updates from the source by only retrieving lookup changes since the last poll.

Hi @Sergio Ferragut In general yes. At the end I’ve used sequence of delete-create to replace content of static map lookups for regression tests. Thank you
