Clojure core.async: coordinating producer and consumer work without manual thread management
Use core.async channels and go blocks to coordinate Clojure work with blocking-style syntax while parking threads, not blocking OS threads.
clojureClojure core.async: Why Blocking Calls in go Blocks Stall Your Thread Pool
Learn how core.async channels and go blocks coordinate asynchronous work, choose the right buffer for back-pressure, and avoid the most common production mistake: blocking inside a go block.
Choosing Between core.async Channels, Agents, and Futures for Concurrent State in Clojure
A decision guide comparing Clojure's core.async channels, agents, and futures for concurrent state, with a concrete agent‑based metrics example and validation steps.
Harnessing ClojureScript Core.Async for Responsive Web Streams
Learn how to use ClojureScript’s core.async channels to build non‑blocking, composable data streams in the browser. A step‑by‑step example, trade‑offs, and practical checks are included.
clojurescriptcore.async Retry Strategy: Avoiding Duplicate Writes Without Idempotency Keys
core.async Retry Strategy: Avoiding Duplicate Writes Without Idempotency Keys In a ClojureScript application that uses core.async to serialize side effects, a common pattern is to re‑queue a failed operation on a channel to retry later. The goal is to guarantee that the underlying write – e.g. a database insert or an HTTP POST – is performed at most once, ev
Main thread blocking during high-volume concurrent requests in ClojureScript
Execution Latency in Single-Threaded Event Loop ClojureScript inherits the single-threaded event loop architecture of its host environment. When handling concurrent requests, operations are interleaved rather than executed in parallel. This design creates a potential bottleneck when CPU-intensive computations are performed within the main execution path. Int
Event loop blocking limits during CPU-intensive go-blocks
ClojureScript relies on the single-threaded event loop of the JavaScript host environment. While core.async provides go-blocks to manage asynchronous flows via state machines, these blocks are designed to yield during channel operations rather than preempting long-running synchronous computations. When a go-block contains a heavy CPU-bound task—such as a com
