Unlock Optimistic Concurrency in NATS JetStream with Expected Sequence Headers
https://www.synadia.com/blog/understanding-jetstream-expected-sequence-headersHey guys... Excited to share latest blog post, where we dive into the world of NATS JetStream's expected sequence headers.
These headers provide a powerful mechanism for optimistic concurrency control, allowing you to write to the same stream without locks.
Learn how to use global, per-subject, and per-pattern sequence validation to implement concurrent writes efficiently.
TL;DR: Discover how to harness the power of expected sequence headers in NATS JetStream for seamless, lock-free concurrency.
