gravitino.api.function.function_impl.FunctionImpl¶

class gravitino.api.function.function_impl.FunctionImpl(language: Language, runtime: RuntimeType, resources: FunctionResources | None = None, properties: Dict[str, str] | None = None)¶

Bases: ABC

Base class of function implementations.

A function implementation must declare its language and optional external resources. Concrete implementations are provided by SQLImpl, JavaImpl, and PythonImpl.

__init__(language: Language, runtime: RuntimeType, resources: FunctionResources | None = None, properties: Dict[str, str] | None = None)¶

Construct a FunctionImpl.

Args:: language: The language of the function implementation. runtime: The runtime of the function implementation. resources: The resources required by the function implementation. properties: The properties of the function implementation.
Raises:: ValueError: If language or runtime is not set.

Methods

`__init__`(language, runtime[, resources, ...])	Construct a FunctionImpl.
`language`()	Returns the implementation language.
`properties`()	Returns the additional properties of this implementation.
`resources`()	Returns the external resources required by this implementation.
`runtime`()	Returns the target runtime.

class Language(value, names=<not given>, *values, module=None, qualname=None, type=None, start=1, boundary=None)¶

Bases: Enum

Supported implementation languages.

JAVA = 'JAVA'¶: Java implementation.

PYTHON = 'PYTHON'¶: Python implementation.

SQL = 'SQL'¶: SQL implementation.

class RuntimeType(value, names=<not given>, *values, module=None, qualname=None, type=None, start=1, boundary=None)¶

Bases: Enum

Supported execution runtimes for function implementations.

SPARK = 'SPARK'¶: Spark runtime.

TRINO = 'TRINO'¶: Trino runtime.

classmethod from_string(value: str) → RuntimeType¶

Parse a runtime value from string.

Args:: value: Runtime name.
Returns:: Parsed runtime.
Raises:: ValueError: If the runtime is not supported.

language() → Language¶: Returns the implementation language.

properties() → Dict[str, str]¶: Returns the additional properties of this implementation.

resources() → FunctionResources¶: Returns the external resources required by this implementation.
