+
+Nodata is a simple binary that consists of two parts:
+
+1. Data ingest
+2. Data storage
+3. Data aggregation
+4. Data API / egress
+
+## Data ingest
+
+Nodata presents a simple protobuf grpc api for ingesting either single events or batch
+
+## Data storage
+
+Nodata stores data locally in a parquet partitioned scheme
+
+## Data aggregation
+
+Nodata accepts wasm routines for running aggregations over data to be processed
+
+## Data Egress
+
+Nodata exposes aggregations as apis, or events to be sent as grpc streamed apis to a service.
