Queries with compound conditions

[ptaoussanis]

Hi Rahul,

@LeonardoBorges recently added support for expressions with #73 - could that be what you're looking for?

The changes are currently on the dev branch and Clojars as [com.taoensso/faraday "1.9.0-alpha2"]

Thanks! That sets up the basic infrastructure for what I want. I just need to adapt whatever was done to update-item and put-item to query.

Sounds good, PR welcome!

As I read through the query code and consulted the AWS docs, I realized that I can accomplish my specific query with the IN operator. But the fact still remains that faraday is currently using the legacy way of filtering queries.

I suggest that we consider the current query-filter parameter as a mini-DSL that is compiled into a condition expression (the new API for DynamoDB). I'll leave this issue open as a feature request for updating faraday to implement this DSL to maintain the simple interface while keeping it up to date with the updated DynamoDB API.

It would seem like the original request is something that can be handled with filter expressions, which I added on #76.

@rahulmutt Could you take a look at these tests and see if it provides what you were aiming for?

I believe this has been addressed by @ricardojmendez's recent work so closing.

@rahulmutt: please feel free to reopen if you're still having trouble.
