summary

DalmatinerDB is a time‑series database written from scratch on Riak Core that replaces Redis in a metrics pipeline, adds a PostgreSQL indexer for dimensions, and ships as open source used by Data Loop. Implementation in Erlang yields far fewer worker crashes, linear cluster scaling, and a single‑node ingest of about 3 million metrics per second. Storage uses whisper‑style flat files on ZFS for extreme compression and the query engine returns single‑host 12‑hour aggregates in ~13–21 ms.
