So the upsides of Vespa over Elasticsearch are speeding up the rate at which it scales? Ah, that seems reasonable for a company this size, but is there something in there that's of use for Startups?
This blog post shows how Elasticsearch was used to reindex a 136TB dataset with 36B documents[1], so I'm unsure exactly where except for Google/Yahoo Scale companies Vespa is of use. I would like to understand howto utilize it though without adding an umnanagable complexity.
EDIT: Maybe a Vespa Cloud startup, that abstracts the management and makes "Scalability as a Service" by utilizing other Cloud providers.
