In this case, this `__call__` is what **FastAPI** will use to check for additional parameters and sub-dependencies, and this is what will be called to pass a value to the parameter in your *path operation function* later.

## Parameterize the instance { #parameterize-the-instance }

start using the least used cluster. This expansion strategy works endlessly, so you can perpetually expand your clusters as needed.  When you restart, it is immediate and non-disruptive to the applications. Each group of servers in the command-line is called a pool. There are 2 server pools in this example. New objects are placed in server pools in proportion to the amount of free space in each pool. Within each pool, the location of the erasure-set of drives is determined based on a deterministic hashing...

Once a new property has been introduced, you need to consider what its conventions will be.

A convention is a value for a property that is used when no other opinion has been provided.  Sometimes conventions are called "default values", but this can be confusing because no property has a "default value" upon creation (except for collection-like properties, which start empty).  Conventions need to be explicitly set on a property.
