You can only "warm up" your views querying them. You can use cURL from your command line. This will cause the creation of an index file per design document. This index file is updated each time another query is made on a view defined inside the design document. A view is never updated when you insert a document, but when you query the view itself. For performance reasons you can choose to avoid the index update when you query a view, but the results will not include the documents inserted since last query. Anyway you must force this behavior using a query parameter. The index creation requires time, but the index update is generally fast enough. So, the best approach is querying all the views when you deploy the application, because indexing is a slow process. You can do that with a bash script. Eventually, you can query multiple views at the same time, so you can benefit of a multi-core architecture.
