- What do Etcd, Consul, and Zookeeper do?
  - Service Registration:
    - Host, port number, and sometimes authentication credentials, protocols, versions
      numbers, and/or environment details.
  - Service Discovery:
    - Ability for client application to query the central registry to learn of service location.
  - Consistent and durable general-purpose K/V store across distributed system.
    - Some solutions support this better than others.
    - Based on Paxos or some derivative (i.e. Raft) algorithm to quickly converge to a consistent state.
    - Centralized locking can be based on this K/V store.

We're working on a project that uses the Datomic Pull API to pull specific attributes out of Datomic entities. Here's an example of query that uses the Pull API:

(d/q '[:find [(pull ?e [:sales/deal_number :sales/deal_close_date :sales/state]) ...] 
       :in $ ?date 
       :where [?e :sales/deal_close_date ?d _ _] [(> ?d ?date)]] 
       db 
       (days-ago-at-midnight 1))
