python - How can I use different pipelines for different spiders in a single Scrapy project

I have a scrapy project which contains multiple spiders. Is there any way I can define which pipelines to use for which spider? Not all the pipelines i have defined are applicable for every spider.

Thanks

Just remove all pipelines from main settings and use this inside spider.

This will define the pipeline to user per spider

class testSpider(InitSpider):
    name = 'test'
    custom_settings = {
        'ITEM_PIPELINES': {
            'app.MyPipeline': 400
        }
    }
