FileCreatedTrigger

Trigger that listens for new files created in a Google Drive folder

Monitors a specified folder for newly created files and emits an event for each new file detected. The trigger uses polling to check for new files based on their creation time.

yaml
type: "io.kestra.plugin.googleworkspace.drive.FileCreatedTrigger"

Examples

Monitor a folder for any new file

yaml
id: google_drive_file_trigger
namespace: company.team

tasks:
  - id: process_file
    type: io.kestra.plugin.core.log.Log
    message: "New file created: {{ trigger.name }} ({{ trigger.id }})"

triggers:
  - id: watch_folder
    type: io.kestra.plugin.googleworkspace.drive.FileCreatedTrigger
    serviceAccount: "{{ secret('GCP_SERVICE_ACCOUNT') }}"
    folderId: "1a2b3c4d5e6f7g8h9i0j"
    interval: PT5M

Monitor for specific MIME types with filters

yaml
id: google_drive_pdf_trigger
namespace: company.team

tasks:
  - id: download_pdf
    type: io.kestra.plugin.googleworkspace.drive.Download
    serviceAccount: "{{ secret('GCP_SERVICE_ACCOUNT') }}"
    fileId: "{{ trigger.id }}"

triggers:
  - id: watch_pdfs
    type: io.kestra.plugin.googleworkspace.drive.FileCreatedTrigger
    serviceAccount: "{{ secret('GCP_SERVICE_ACCOUNT') }}"
    folderId: "1a2b3c4d5e6f7g8h9i0j"
    mimeTypes:
      - application/pdf
      - application/vnd.google-apps.document
    interval: PT10M

Monitor entire Drive with owner filter

yaml
id: google_drive_owner_trigger
namespace: company.team

tasks:
  - id: notify
    type: io.kestra.plugin.notifications.slack.SlackIncomingWebhook
    url: "{{ secret('SLACK_WEBHOOK') }}"
    payload: |
      {
        "text": "New file by {{ trigger.owners[0].displayName }}: {{ trigger.name }}"
      }

triggers:
  - id: watch_my_files
    type: io.kestra.plugin.googleworkspace.drive.FileCreatedTrigger
    serviceAccount: "{{ secret('GCP_SERVICE_ACCOUNT') }}"
    ownerEmail: "user@company.com"
    interval: PT15M

type *object

resetOnSuccess boolean

Default true

Whether to reset the evaluation results of SLA conditions after a first successful evaluation within the given time period.

By default, after a successful evaluation of the set of SLA conditions, the evaluation result is reset, so, the same set of conditions needs to be successfully evaluated again in the same time period to trigger a new execution. This means that to create multiple executions, the same set of conditions needs to be evaluated to true multiple times. You can disable this by setting this property to false so that, within the same period, each time one of the conditions is satisfied again after a successful evaluation, it will trigger a new execution.

timeWindow TimeWindow

Default

{
  "type": "DURATION_WINDOW"
}

Define the time period (or window) for evaluating preconditions.

You can set the type of sla to one of the following values:

DURATION_WINDOW: this is the default type. It uses a start time (windowAdvance) and end time (window) that are moving forward to the next interval whenever the evaluation time reaches the end time, based on the defined duration window. For example, with a 1-day window (the default option: window: PT1D), the SLA conditions are always evaluated during 24h starting at midnight (i.e. at time 00: 00: 00) each day. If you set windowAdvance: PT6H, the window will start at 6 AM each day. If you set windowAdvance: PT6H and you also override the window property to PT6H, the window will start at 6 AM and last for 6 hours — as a result, Kestra will check the SLA conditions during the following time periods: 06: 00 to 12: 00, 12: 00 to 18: 00, 18: 00 to 00: 00, and 00: 00 to 06: 00, and so on.
SLIDING_WINDOW: this option also evaluates SLA conditions over a fixed time window, but it always goes backward from the current time. For example, a sliding window of 1 hour (window: PT1H) will evaluate executions for the past hour (so between now and one hour before now). It uses a default window of 1 day.
DAILY_TIME_DEADLINE: this option declares that some SLA conditions should be met "before a specific time in a day". With the string property deadline, you can configure a daily cutoff for checking conditions. For example, deadline: "09: 00: 00" means that the defined SLA conditions should be met from midnight until 9 AM each day; otherwise, the flow will not be triggered.
DAILY_TIME_WINDOW: this option declares that some SLA conditions should be met "within a given time range in a day". For example, a window from startTime: "06: 00: 00" to endTime: "09: 00: 00" evaluates executions within that interval each day. This option is particularly useful for declarative definition of freshness conditions when building data pipelines. For example, if you only need one successful execution within a given time range to guarantee that some data has been successfully refreshed in order for you to proceed with the next steps of your pipeline, this option can be more useful than a strict DAG-based approach. Usually, each failure in your flow would block the entire pipeline, whereas with this option, you can proceed with the next steps of the pipeline as soon as the data is successfully refreshed at least once within the given time range.
