Class swarmauri_middleware_bulkhead.BulkheadMiddleware.BulkheadMiddleware
swarmauri_middleware_bulkhead.BulkheadMiddleware.BulkheadMiddleware
BulkheadMiddleware(max_concurrency=10, **kwargs)
Bases: MiddlewareBase
Bulkhead middleware implementation to control concurrency isolation.
This middleware restricts the maximum number of concurrent requests to prevent resource overload. It uses a semaphore to manage the concurrency level.
ATTRIBUTE | DESCRIPTION |
---|---|
max_concurrency |
int = 10 # Maximum number of concurrent requests
TYPE:
|
_semaphore |
Semaphore # Semaphore for concurrency control
TYPE:
|
Initializes the BulkheadMiddleware with specified concurrency limit.
PARAMETER | DESCRIPTION |
---|---|
max_concurrency
|
Maximum number of concurrent requests allowed
TYPE:
|
logger
|
Optional logger instance to use for logging

dispatch(request, call_next)
Dispatches the request while controlling concurrency using a semaphore.
This method uses a semaphore to limit the number of concurrent requests. If the maximum concurrency is reached, the request will wait until a slot becomes available.
PARAMETER | DESCRIPTION |
---|---|
request
|
The incoming request object to be processed
TYPE:
|
call_next
|
A callable that invokes the next middleware in the chain
TYPE:
|
RETURNS | DESCRIPTION |
---|---|
Any
|
The response object after all middlewares have processed |
Any
|
the request |
