In ClickHouse you can do

    INSERT INTO table FORMAT JSONEachRow {"key": 123}

It works with all other formats as well.

Plus, it is designed in a way so you can make an INSERT query and stream the data, e.g.:

    clickhouse-client --query "INSERT INTO table FORMAT Protobuf" < data.protobuf

    curl 'https://example.com/?query=INSERT...' --data-binary @- < data.bson
