MongoDB Scality (Janelia's KVAutobus)

(development paused due to throughput issues)

Janelia has tested a petabyte-scale ordered key-value store called KVAutobus. KVAutobus provides a simple HTTP API that fulfills DVID's ordered key-value store interface. Under the hood, the system combines MongoDB, for fast indexing and storage of key-value pairs below a certain size, and Scality, a petabyte-scale object store.
