Onboard to n8n & Tech stack details

Questions

Helo,

I have couple of questions on n8n workflows.
Currently we’re using Camunda workflows and planning to onboard n8n.

  1. What is the tech stack using in n8n?
  2. How workflows will run in engine(Similar to Camunda engine) and which technology that you’re using to run Engine?
  3. Want to understand on the workflow performance?
  4. Can we embedded Rules(DMN)/Create our own rules with in n8n workflows?
  5. Can we update the variable for running instance?
  6. Do you have any archival strategy?
  7. Can we create user task node and timer for waiting the node response?
  8. Do you support any open java library to integrate with Micro services to build the own n8n engine(Again similar to Camunda)
  9. Can we run workflows parallelly?

Share the output returned by the last node

Team, Do we have any updates on this

Hi @ashok_kumar ,

Happy to hear you’re looking to try out n8n.

n8n runs primarily on Node.js as JavaScript runtime environment, and does not have a dedicated workflow execution engine like Camunda, and does not support any open Java libraries at the moment.
You can explore our GitHub repo for more details: GitHub - n8n-io/n8n: Free and source-available fair-code licensed workflow automation tool. Easily automate tasks across different services.

Workflow performance will vary a lot depending on whether you are self-hosting (and how) or using our cloud version. What set-up do you have in mind?
The same goes for running multiple workflows parallelly - n8n can easily support this but how many will depend on how heavy these are and how you’re deploying n8n.

n8n doesn’t support embedded rules but it does allow for user-limited access to workflows, credentials and projects which provides customisation - Account types | n8n Docs. It also supports custom variables - Create custom variables | n8n Docs.

Regarding archival strategy - We create daily backups of workflows for users in the cloud plans that can be retrieved for up to 90 days. - is this what you meant?

Yes, you can implement our Wait node to wait for a webhook reply before proceeding with the workflow execution - Wait | n8n Docs

To test out if n8n is right for the integrations you have in mind I suggest signing up for a free trial in our Cloud service - n8n Plans and Pricing - n8n.io or, if you are more interested in self-hosting, giving us a try through our Community Version, which is free - n8n Hosting Documentation and Guides | n8n Docs
