```
Maximal number of parallel requests going through this bulkhead. When the limit is reached, additional requests are enqueued.

Parameters:

limit - maximal number of parallel calls, defaults is 10

Returns:

updated builder instance

queueLength
```
public Bulkhead.Builder queueLength(int queueLength)
```
Maximal number of enqueued requests waiting for processing. When the limit is reached, additional attempts to invoke a request will receive a BulkheadException.

Parameters:

queueLength - length of queue

Returns:

updated builder instance

name
```
public Bulkhead.Builder name(String name)
```
A name assigned for debugging, error reporting or configuration purposes.

Parameters:

name - the name

Returns:

updated builder instance

cancelSource
```
public Bulkhead.Builder cancelSource(boolean cancelSource)
```
Policy to cancel any source stage if the value return by FtHandler.invoke(java.util.function.Supplier<? extends java.util.concurrent.CompletionStage<T>>) is cancelled. Default is true; mostly used by FT MP to change default.

Parameters:

cancelSource - cancel source policy

Returns:

updated builder instance

config

public Bulkhead.Builder config(Config config)

Load all properties for this bulkhead from configuration.

Configuration
key	default value	description
