+**************************************

+Specifies the maximum number of connections, across all simultaneous
+sessions, is allowed to make to the local node. This setting is relevant
+when the local node has shards, such as Citus on Single Node.
+
+By default, the value is automatically set equal to the half of the node's
+own ``max_connections``.
+
+The setting provides similar throttling as :ref:`max_shared_pool_size`, however
+only for local node. The goal is that Citus should refrain to use all the avaliable
+connection slots in ``max_connections`` and allow the client backends (e.g.,
+``psql``) to have enough space to connect. The value -1 disables throttling.
