This variable has been deprecated and will be removed in a
future release. It is replaced by
INITIAL_DISABLED_NODE_TASKS.
Whether this node should act as a query coordinator. Query coordinators are responsible for sending subqueries to storage nodes and combining the results. In clusters with "httponly" nodes (as described above), it often makes sense to set this to false for non-httponly nodes.
See ENABLE_QUERY_LOAD_BALANCING and
NODE_ROLES for more information.
