What is Kestra ?

Kestra is an infinitely scalable orchestration and scheduling platform, creating, running, scheduling, and monitoring millions of complex pipelines.

  • 🔀 Any kind of workflow: Workflows can start simple and progress to more complex systems with branching, parallel, dynamic tasks, flow dependencies
  • 🎓‍ Easy to learn: Flows are in simple, descriptive language defined in YAML—you don't need to be a developer to create a new flow.
  • 🔣 Easy to extend: Plugins are everywhere in Kestra, many are available from the Kestra core team, but you can create one easily.
  • 🆙 Any triggers: Kestra is event-based at heart—you can trigger an execution from API, schedule, detection, events
  • 💻 A rich user interface: The built-in web interface allows you to create, run, and monitor all your flows—no need to deploy your flows, just edit them.
  • Enjoy infinite scalability: Kestra is built around top cloud native technologies—scale to millions of executions stress-free.

Example flow:

id: my-first-flow
namespace: my.company.teams

inputs:
  - type: FILE
    name: uploaded
    description: A Csv file to be uploaded through API or UI

tasks:
  - id: archive
    type: io.kestra.plugin.gcp.gcs.Upload
    description: Archive the file on Google Cloud Storage bucket
    from: "{{ inputs.uploaded }}"
    to: "gs://my_bucket/archives/{{ execution.id }}.csv"

  - id: csvReader
    type: io.kestra.plugin.serdes.csv.CsvReader
    from: "{{ inputs.uploaded }}"

  - id: fileTransform
    type: io.kestra.plugin.scripts.nashorn.FileTransform
    description: This task will anonymize the contactName with a custom nashorn script (javascript over jvm). This show that you able to handle custom transformation or remapping in the ETL way
    from: "{{ outputs.csvReader.uri }}"
    script: |
      if (row['contactName']) {
        row['contactName'] = "*".repeat(row['contactName'].length);
      }

  - id: avroWriter
    type: io.kestra.plugin.serdes.avro.AvroWriter
    description: This file will convert the file from Kestra internal storage to avro. Again, we handling ETL since the conversion is done by Kestra before loading the data in BigQuery. This allow you to have some control before loading and to reject wrong data as soon as possible.
    from: "{{ outputs.fileTransform.uri }}"
