To write data to GreptimeDB, you'll need to establish a connection first.
Automatic Schema Generation
GreptimeDB provides schemaless writing that automatically creates schemas for your data, so that you don't need to create tables in advance. The table and columns will be created and added automatically when writing data with protocol gRPC supported by SDKs, InfluxDB, OpenTSDB and Prometheus remote write. When necessary, GreptimeDB automatically adds the required columns to ensure that the user's data is correctly saved.
