Selling data using apache kafka

I have an architecture question.

I buid a website where people can sell data.

Below is the overall logic that I used, however, I am afraid that I have picked the wrong tech stack

right now I am using mysql/node/angular.

Would this tech stack work? (pls explain why it wont work)

Do you recommend switching to apache?

What techstack do you recommend?

Here is the logic I used, feel free to comment on this aswell

channel : a table that stores the type of data that you want to sell.

example data:

first name, last name, state, zip code, cigar smoker?, diabetic, male, female …

channel subscription: a table that stores who is interested in buying the data

This is my business logic:

  1. Client A creates the channel XYZ where he describes the data that will be sold through it.

  2. Client B subscribes to channel XYZ.

2.1) Client C subscribes to channel XYZ.

2.2) Client D subscribes to channel XYZ.

  1. Client A sends a ping to our system saying, ‘Hi, I have 30,000 data records I want to sell through channel XYZ. The lowest amount I am willing to sell the data for is $5. Does anyone want to buy this data?’

  2. Our system pings the users subscribe to channel XYZ saying. ‘hi, there are 30,000 records that match the criteria to channel XYZ, do you want to submit a bid?’

  3. The clients subscribed to channel XYZ submit their bid

  4. Our system looks at the submitted bids for channel XYZ, if it meets the minimum, the system:

  • sends a pingback to the seller ‘we have a buyer for your data’
  1. Our system listens for a request from the seller Once a valid API call is registered, the data is validated, saved, and send to the buyer


  • is apache kafka good for this?
  • is node.js good with this? ( i dont really understand if there are different flavors of apache kafka… one of them being with node.js, the other one with python)
