Hello @meg261995, sorry for the delay in replying here.

Unfortunately, if you will not send impression data, then personalization will not behave as expected. Impression information is used in the model to understand what items are relevant to a specific user, which powers personalization. You can check out this blog post to deeper understand how personalization works: https://blog.metarank.ai/personalized-search-with-metarank-and-elasticsearch-a5a098548da7

Hey,

I will be sending impression data, which is all the products shown to the user. In the demo along with impression data, real time interaction is also fed.. This is a multi step process. My question was whether this was needed or not. Impression data is definitely needed, no doubt here

The clickstream is also needed as it separates relevant items from irrelevant ones for the user and it's connected to the impression data sent before the click. You can't omit this data as well as the model will not behave as expected. Although you can batch upload impressions and clickthroughs later, you will not get the real-time personalization.

However, if you don't need personalization per se, you can create a model that does not depend on click events, in this case 'personalization' will be generic for all users making requests, but you won't need to send impressions and clicks in real time and can just re-train the model when needed.
