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