Hi Tim,

Thanks for the great questions and feedback. Taking them in order:

1. We are aware of the problems on the AWS Marketplace page, and are working with AWS to improve it. In the meantime happy to help out here!
2. Recent query results are stored in an LRU cache until you consume them.
3. The caching story gets substantially better in Cloud with the introduction of valcache and the EFS cache. We have updated [the docs](https://docs.datomic.com/cloud/operation/caching.html) to cover this.
4. Squuids are not really needed now that Datomic has [adaptive indexing](http://blog.datomic.com/2014/03/datomic-adaptive-indexing.html). That said, the code is [in the Clojure cookbook](https://github.com/clojure-cookbook/clojure-cookbook/blob/master/01_primitive-data/1-24_uuids.asciidoc) if you want it.
5. Not sure, let me get back to you.
