Joining data from other source while returning response

let's say we have indexed price and availability in the elasticsearch. And let's say we are working on a high frequency website/sale day it will be impossible/very time consuming to keep up the indexing with current stock/price. To mitigate this i read
this blog. Where price and stock are kept in memory and are dynamically updated by a separate pipeline. Is this kind of integration possible with elasticsearch? I tried asking similar question
here but did not get a reply.
