While being able to offload to statsd/graphite/raygun/... is great, a "state of the nation" dashboard would be really handy.

This could show requests/sec, wait times, "slow" requests, auth failures, live access map, recent exceptions, known issues (e.g. can't connect to redisX/mssqlY)

Much like you have created a RedisSentinel object ... I have a need for a RedisCluster object that supports the new feature which is coming in v3.0. Thanks.

Being able to bulk insert/copy would be cool.

Adding support in so I could just take a list and

Db.BulkCopy(listOfObjects);

would be pretty sweet.

SqlServer has the bulkCopy object, postgres has the copy command, sqlite has import (although no idea how well that works) , and mysql...well...who cares (i don't know what they have)

Having a single interface for bulk copying objects into different databases I think would be a nice feature for ormlite. (not sure how feasible)

Currently redis client is not async - this is wasting valuable resources on the server side. As far as I understand async support is currently only there for service clients and not redis

Support to automatically update a db schema based on changes such as: adding/renaming and possibly removing a property or class.

Building upon swagger feature, (but possibly re-engineering)

Support to include:
- complex (nested) DTO's and array
- markdown documentation (for detailed description)
- role/access based display (so only authorised endpoints are displayed)
- rebranding support
- ability to install nuget package without /docs folder (so as to get annotations, but not html in a model lib)

The c# SDK is seriously lagging in documentation. By that I mean IntelliSense documentation: it would be awsome with some "in line" documentation for methods and properties in the SDK

support localization in messages for validations or any other messages sent to the client

"OpenID Connect (OIDC) is an authentication layer on top of OAuth 2.0, an authorization framework." The benefit to developers and consumers is a more simplified way to add a new Auth provider which would provide some standard user info.

Swagger now support oAuth login page to create a access_token to apply to a oAuth protected API: http://developers-blog.helloreverb.com/enabling-oauth-with-swagger/

Please could you add a similar capability to ServiceSatck.SwaggerFeature that enables SS developers to add a similar capability to their own APIS that are protected by oAuth.

I've just stumbled upon Facebook's GraphQL and it's pretty slick.
The ability to query a ServiceStack endpoint using GraphQL would be a great addition (maybe similar to AutoQuery?) If ORMLite could also populate an object graph using a GraphQL query...

Provide async overloads for caching API so async operations can construct the cache.

Currently Oracle is not a supported OrmLite provider that's listed on:
http://servicestack.net/download

Vote for this feature request if you would like to see the OrmLite Oracle provider officially supported.

Many serious architecture work on Restful+JSON and consumers are more and more asking for some WADL to industrialize their exchanges.
This may be a main criteria to select a ServiceStack.
So i suggest the WADL implementation directly on ServiceStack.

The AutoQuery plugin is great especially for use with many front end grids/tables, however it lacks the ability to Group By. Can you implement it to have feature parity to work with many of the front end grid components (ie kendo grid/devexpress/etc)?
