Design: Notify user about new apartments he might be interested in

[OrAbramovich]

New feature: the platform should be able to notify (notification + email) a registered user about new apartments he might be interested in according to his last searches. The task is writing a design document for the feature.

[OrAbramovich]

The suggestion should be based on past history search.

[OrAbramovich]

Estimated time: 2 hours.

a sektch for the design:
save in a tree formation all the users acoording to search:
have 1 main json that saves an array of data for every country, every countrywill save an array of cities, and so on for each search parameter.

• search history{

  • country array [

    • city array [

      • price_range array [

        • users array [
          * user1,
          * user2,
          * user3

        ]

      ]

    ]

  ]

}
when ever a new apartment is added we will check the coorsopnding search in the search tree to find the list of users that searched for this kind of apartment.

what do you think of this as a base?

i think i am finished, waiting for OK from @OrAbramovich

Hi @chananbental ,

First of all - it looks good. We can actually derive the API and it looks that your design fits the current flow of the system.

In my opinion, the following are missing:

1. The actual flow (e.g apartment is added -> the system looks for relevant searches (immediately/once a...).

2. More details (e.g "we need to save the searchs parameters: location, price range, number of rooms, basically all info used in searchs" - how? what is the structure?").

3. I think it would be great if you could write other implementation alternatives along with the pros and cons of each one so we can understand the reasons and considerations for choosing the specific one.

What do you think?

[chananbental]

Sounds like a good idea.
Ill get on it once i ginish the nust, should be very soon
