Authentication

Authentication occurs when a user attempts to connect to the database. GreptimeDB offers a simple built-in mechanism for authentication, allowing users to configure either a fixed account for convenient usage or an account file for multiple user accounts. By passing in a file, GreptimeDB loads all users listed within it.

GreptimeDB reads the user and password on each line using = as a separator, just like a command-line config. For example:

greptime_user=greptime_pwd
alice=aaa
bob=bbb

then start server with --user-provider parameter:

./greptime standalone start --user-provider=static_user_provider:file:<path_to_file>

Now, user alice with password aaa and user bob with password bbb are loaded into GreptimeDB's memory. You can create a connection to GreptimeDB using these user accounts.

Note: The content of the file is loaded into the database while starting up. Modifying or appending the file won't take effect while the database is up and running.
