Create a trigger for a specific table
Create a trigger that processes data from a specific table.
influxdb3 create trigger \
--database DATABASE_NAME \
--token AUTH_TOKEN \
--plugin-filename PLUGIN_FILENAME \
--trigger-spec table:TABLE_NAME \
TRIGGER_NAME
Create a trigger for all tables
Create a trigger that applies to all tables in the specified database.
influxdb3 create trigger \
--database DATABASE_NAME \
--token AUTH_TOKEN \
--plugin-filename <PLUGIN_FILENAME> \
--trigger-spec all_tables \
TRIGGER_NAME
This is useful when you want a trigger to apply to any table in the database, regardless of name.
Create a disabled trigger
Create a trigger in a disabled state.
influxdb3 create trigger \
--disabled \
--database DATABASE_NAME \
--token AUTH_TOKEN \
--plugin-filename <PLUGIN_FILENAME> \
--trigger-spec table:TABLE_NAME \
TRIGGER_NAME
Creating a trigger in a disabled state prevents it from running immediately. You can enable it later when you're ready to activate it.
