The article by aziz abdullaev provided an in-depth case study on optimizing the rendering of a large number of markers on a map for a web application. The task involved handling over 12,000 markers smoothly using the Elixir language, Phoenix LiveView for server-side operations, and Leaflet.js for client-side map interaction. The article began by identifying the two key tasks: fetching data from the database and rendering it on a map. Aziz then detailed the strategies used to split the data fetching and rendering processes, leveraging Elixir's concurrency features and optimizing JavaScript execution on the client side. The final solution included asynchronously fetching data chunks and using a Canvas renderer in Leaflet.js to minimize DOM interactions. The author shared code snippets for both the Elixir and JavaScript portions of the implementation, providing insights into a practical solution for handling large data sets in web applications.
