Unknown Universe

Review “The author brings the subject up to 2015 with the obligatory new discovery combined with a fine history of cosmology, and he makes it clear that our knowledge and ignorance seem to be expanding in parallel. Since satisfying results have yet to turn up, Clark's book ends on a cliffhanger, but readers will be entirely pleased with the experience.” - Kirkus Reviews (starred review)

How it works

Doc fetch goes through Layer's Aerospike pull-through cache; cache hit served the row without touching turbopuffer. The similar query asks Layer for nearest neighbors of the stored product vector — queries don't go through the doc cache, so no cache header is set.
