A nice implementation. A few more checks are needed to ensure queue won't get blocked. Please review also the filename/directory name conventions. I think it should all be camelCase.

private readonly limit: number = Infinity,
) { }

public store(data: ExecutionMetaData<T>): this {

Please use standard queue method names, like push and pop instead of store and next

Chances are low we will ever have another execution queue implementation than the current one. Therefore the factory here seems like an added complexity. I'd suggest rather to delete this file, and implement a static method static create<T>(limit: number): ExecutionQueue<T> directly in the ExecutionQueue class.

Bulkhead/Bulkhead.ts doesn't sound nice. Maybe just bulkhead/index.ts ?

Same as for queue implementation, this factory is not of much use taking into account there won't be another bulkhead implementations. Now it looks like an added complexity. I'd suggest that we implement a static create method directly in the bulkhead class.

Not sure if async is needed here.

private async execute(method: (...args: any[]) => Promise<T>, args: any[]) {
this.inExecution += 1;

const result = method(...args);

The provided method might throw an error, thus breaking our queue execution.

this.callNext();
};

result.then(afterExecution, afterExecution);

What if the method never resolves? It will stay forever in the queue and potentially might block the queue. I think we might need an additional option to setup a timeout for the execution. Could we use the @timeout from current library? Either as a decorator, or directly as a method.
