The open big data serving engine: Store, search, rank and organize big data

Active discussion:

This sounds very cool, but also a lot like ElasticSearch. Is there a comparison somewhere?

(There a little matrix at the bottom of their page, but it's ... marketing-y).

A big pro seems ability to split/merge indexes (like solr). Enables easier scaling.

Feels like "Live Reconfiguration" is at least partially true for ES + relational dbs

Any reason why it's named the same as the Italian scooter brand?

It's based on "VErtical Search PlAtform". A bit of a contrived acronym perhaps ... it's been known as Vespa internally in Oath/Yahoo for a long time.
