zen_store_interface
ZenML Store interface.
ZenStoreInterface (ABC)
ZenML store interface.
All ZenML stores must implement the methods in this interface.
The methods in this interface are organized in the following way:
-
they are grouped into categories based on the type of resource that they operate on (e.g. stacks, stack components, etc.)
-
each category has a set of CRUD methods (create, read, update, delete) that operate on the resources in that category. The order of the methods in each category should be:
-
create methods - store a new resource. These methods should fill in generated fields (e.g. UUIDs, creation timestamps) in the resource and return the updated resource.
- get methods - retrieve a single existing resource identified by a unique key or identifier from the store. These methods should always return a resource and raise an exception if the resource does not exist.
- list methods - retrieve a list of resources from the store. These methods should accept a set of filter parameters that can be used to filter the list of resources retrieved from the store.
- update methods - update an existing resource in the store. These methods should expect the updated resource to be correctly identified by its unique key or identifier and raise an exception if the resource does not exist.
- delete methods - delete an existing resource from the store. These methods should expect the resource to be correctly identified by its unique key or identifier. If the resource does not exist, an exception should be raised.
Best practices for implementing and keeping this interface clean and easy to maintain and extend:
- keep methods organized by resource type and ordered by CRUD operation
- for resources with multiple keys, don't implement multiple get or list methods here if the same functionality can be achieved by a single get or list method. Instead, implement them in the BaseZenStore class and have them call the generic get or list method in this interface.
- keep the logic required to convert between ZenML domain Model classes and internal store representations outside the ZenML domain Model classes
- methods for resources that have two or more unique keys (e.g. a Project
is uniquely identified by its name as well as its UUID) should reflect
that in the method variants and/or method arguments:
- methods that take in a resource identifier as argument should accept
all variants of the identifier (e.g.
project_name_or_uuidfor methods that get/list/update/delete Projects) - if a compound key is involved, separate get methods should be
implemented (e.g.
get_pipelineto get a pipeline by ID andget_pipeline_in_projectto get a pipeline by its name and the ID of the project it belongs to)
- methods that take in a resource identifier as argument should accept
all variants of the identifier (e.g.
- methods for resources that are scoped as children of other resources
(e.g. a Stack is always owned by a Project) should reflect the
key(s) of the parent resource in the provided methods and method
arguments:
- create methods should take the parent resource UUID(s) as an argument
(e.g.
create_stacktakes in the project ID) - get methods should be provided to retrieve a resource by the compound key that includes the parent resource key(s)
- list methods should feature optional filter arguments that reflect the parent resource key(s)
- create methods should take the parent resource UUID(s) as an argument
