## Examples
|
|
|
|
The following examples show how to use the `influxdb3 create trigger` command to create triggers in different scenarios.
|
|
|
|
|
|
- {{% code-placeholder-key %}}`DATABASE_NAME`{{% /code-placeholder-key %}}: Database name
|
|
- {{% code-placeholder-key %}}`AUTH_TOKEN`{{% /code-placeholder-key %}}:
|
|
Authentication token
|
|
- {{% code-placeholder-key %}}`TRIGGER_NAME`{{% /code-placeholder-key %}}:
|
|
Name of the trigger to create
|
|
- {{% code-placeholder-key %}}`TABLE_NAME`{{% /code-placeholder-key %}}:
|
|
Name of the table to trigger on
|
|
|
|
{{% code-placeholders "(DATABASE|TRIGGER)_NAME|AUTH_TOKEN|TABLE_NAME" %}}
|
|
|
|
### Create a trigger for a specific table
|
|
|
|
Create a trigger that processes data from a specific table.
|
|
|
|
<!--pytest.mark.skip-->
|
|
|
|
```bash
|
|
influxdb3 create trigger \
|
|
--database DATABASE_NAME \
|
|
--token AUTH_TOKEN \
|
|
--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.
|
|
|
|
<!--pytest.mark.skip-->
|
|
|
|
```bash
|
|
influxdb3 create trigger \
|
|
--database DATABASE_NAME \
|
|
--token AUTH_TOKEN \
|
|
--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.
|
|
|
|
<!--pytest.mark.skip-->
|
|
|
|
```bash
|
|
influxdb3 create trigger \
|
|
--disabled \
|
|
--database DATABASE_NAME \
|
|
--token AUTH_TOKEN \
|
|
--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.
