Getting Started

Download sample configuration and data

Create a new empty directory and run the commands below. This will download a sample configuration file and a sample NY Taxi Dataset file.

curl -o dozer-config.yaml https://raw.githubusercontent.com/getdozer/dozer-samples/main/connectors/local-storage/dozer-config.yaml
curl --create-dirs -o data/trips/fhvhv_tripdata_2022-01.parquet https://d37ci6vzurychx.cloudfront.net/trip-data/fhvhv_tripdata_2022-01.parquet

Run Dozer binary

dozer -c dozer-config.yaml

Dozer will start processing the data and populating the cache. You can see a progress of the execution from the console.

Query the APIs

When some data is loaded, you can query the cache using gRPC or REST

# gRPC
grpcurl -d '{"query": "{\"$limit\": 1}"}' -plaintext localhost:50051 dozer.generated.trips_cache.TripsCaches/query

# REST
curl -X POST  http://localhost:8080/trips/query --header 'Content-Type: application/json' --data-raw '{"$limit":3}'

Alternatively, you can use Postman to discover gRPC endpoints through gRPC reflection
