The service that redirects metabase queries to the correct metabase engine(s). Each metabase engine in the storage pool is responsible for managing the metadata records from a group of agents. Queries for a file or files do not go directly to the metabase engine but instead are directed to the metabase server. The metabase server redirects the query to the metabase engine that manages the metadata records of the agent that made the query or to which the query is associated. In some cases the metabase server may have to redirect the incoming query to multiple metabase engines.
