GWicke added a comment. Aude's summary is spot on. Our current focus is on html and data-parsoid, but we plan to add more content types like wikitext as well. Serializations of MediaWiki ContentHandler content models would map to separate RESTBase content types. For wikidata this could be a specific JSON type like `application/json;profile=wikidata.org/specs/someschema/1.0`, or perhaps RDF.
> How fast is it (mean response time for the kind of request we will be doing)? You can take a look at HTML revision request latencies here: http://grafana.wikimedia.org/#/dashboard/db/restbase Current mean response time is around 15ms, while the 99% is around 60ms. > Does it support batch loading (to save network roundtrips)? Yes, via SPDY. The provisioned cluster can handle around 10k req/s without Varnish caching, and we are expanding it. > Can we be sure to get the latest revision of an entity all the time (for most > uses cases a small lag after an edit is ok, like what you would get from a > slave database)? Currently you can either directly ask for the latest revision by oldid, or ask for the latest, which should not be more than a few seconds out of date. We might add an additional ability to ask RB to double-check for up-to-date-ness, possibly by setting a `no-cache` header, at the cost of latency. > Is it fast if we just iterate over all pages or just if those are revisions > requested often? Currently only recent revisions (current and some recent history) are stored for all pages. The longer-term goal is to store the entire revision history for each page. Since it is storage and not caching, rarely accessed content has roughly the same access latency as popular content. > Does it have metadata available? Which metadata are you looking for?
