You can read from or write into GreptimeDB using various protocols.
Note that writing data in a specific protocol does not mean that you have to read data with the same protocol. For example, you can write data through gRPC endpoint while using MySQL client to read them.
Please refer to Authentication to learn how to config username and password for GreptimeDB.
Client SDK Libraries
Client libraries provide a convenient way to connect to GreptimeDB and interact with data. They offer functionality for writing and querying data, making it easier to integrate GreptimeDB into your applications. For more information, please refer to the Client Libraries documentation.
