SequentialExecutor
fastkafka.executors.SequentialExecutor
​
A class that implements a sequential executor for processing consumer records.
The SequentialExecutor class extends the StreamExecutor class and provides functionality for running processing tasks in sequence by awaiting their coroutines.
__init__
​
def __init__(self, throw_exceptions: bool = False, max_buffer_size: int = 100000) -> None
Create an instance of SequentialExecutor
Parameters:
throw_exceptions
: Flag indicating whether exceptions should be thrown or logged. Defaults to False.max_buffer_size
: Maximum buffer size for the memory object stream. Defaults to 100_000.
run
​
def run(self, is_shutting_down_f: Callable[[], bool], generator: Callable[[], Awaitable[aiokafka.structs.ConsumerRecord]], processor: Callable[[aiokafka.structs.ConsumerRecord], Awaitable[NoneType]]) -> None
Runs the sequential executor.
Parameters:
is_shutting_down_f
: Function to check if the executor is shutting down.generator
: Generator function for retrieving consumer records.processor
: Processor function for processing consumer records.
