# nodata

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.

# Architecture

## Data flow

Data enteres nodata

1. Application uses SDK to publish data
2. Data is sent over grpc using, a topic, id and data
3. Data is sent to a topic
4. A broadcast is sent that said topic was updated with a given offset
5. A client can consume from said topic, given a topic and id
6. A queue is running consuming each broadcast message, assigning jobs for each consumer group to delegate messages
