Elasticsearch 7 and Elastic Stack - In Depth and Hands On! - Dealing with Concurrency

The video tutorial discusses concurrency issues in web applications, particularly when using Elasticsearch. It explains how simultaneous updates can lead to incorrect data, using a page view count example. The solution, optimistic concurrency control, is introduced, which uses sequence numbers and primary terms to manage updates. A practical demonstration shows how to implement this control, including using the retry on conflict parameter to handle update conflicts automatically.
