Subject [jira] [Created] (COUCHDB-1747) DSL for index creation, validation functions, etc.

Dave Cottlehuber created COUCHDB-1747:
-----------------------------------------

             Summary: DSL for index creation, validation functions, etc.
                 Key: COUCHDB-1747
                 URL: https://issues.apache.org/jira/browse/COUCHDB-1747
             Project: CouchDB
          Issue Type: Improvement
            Reporter: Dave Cottlehuber


Implement a Domain-Specific Language to run within the Erlang VM,
to support native speed filtering, validation, and indexing in
addition to the current in-built JS and erlang ones. Maybe something
that includes http://jsonselect.org/

The DSL would be very simple, deliberately not capable of expressing
all possible algorithms, but can always be efficiently evaluated
within the native VM. This will be faster in general but also avoids
managing a pool of couchjs processes.
