Description

Design documents with matching document IDs, from databases on the same cluster, may share a mutable Javascript environment when using these design document functions: * validate_doc_update

* list

* filter

* filter views (using view functions as filters)

* rewrite

* update

This doesn't affect map/reduce or search (Dreyfus) index functions.
