NSDB (Natural Series DB)
summary
Radicalbit builds NSDB as a time-series serving DB implemented in Scala that uses Akka cluster for distribution, Lucene-style indexing for space (dimensions) and configurable time-slot sharding (example: 15s intervals) that round-robins chunks across N nodes. Beats are immutable timestamped points with dynamic key/value dimensions; writes go through a Flink sink and Avro-compatible ingest, are nonblocking and replicated for HA. A WebSocket publisher fetches history then pushes matching events in real time. Project is open-source roadmap with CLI, REST and language clients.
