<p>Configuration options related to workers which belong in the main config file

|

A Synapse deployment can scale horizontally by running multiple Synapse processes
|

called <em>workers</em>. Incoming requests are distributed between workers to handle higher
|
||||
loads. Some workers are privileged and can accept requests from other workers.</p>
|
||||
<p>As a result, the worker configuration is divided into two parts.</p>
|
||||
<ol>
|
||||
<li>The first part (in this section of the manual) defines which shardable tasks
|
||||
are delegated to privileged workers. This allows unprivileged workers to make
|

request a privileged worker to act on their behalf.</li>
