Horde.DynamicSupervisor.start_link

You're seeing just the function start_link, go back to Horde.DynamicSupervisor module for more information.

start_link(options)

Works like DynamicSupervisor.start_link/1. Extra options are documented here:

:distribution_strategy, defaults to Horde.UniformDistribution but can also be set to Horde.UniformQuorumDistribution. Horde.UniformQuorumDistribution enforces a quorum and will shut down all processes on a node if it is split from the rest of the cluster.
