Response serialization

By default, ROAPI encodes responses in JSON format, but you can request different encodings by specifying the ACCEPT header:

curl -X POST \
    -H 'ACCEPT: application/vnd.apache.arrow.stream' \
    -d "SELECT launch_library_id FROM spacex_launches WHERE launch_library_id IS NOT NULL" \
    localhost:8080/api/sql

ROAPI currently supports the following serialization formats:

• application/json

• application/csv

• application/vnd.apache.arrow.file

• application/vnd.apache.arrow.stream

• application/parquet
