ballerinaAtomic Upserts in PostgreSQL: Eliminate Race Conditions with INSERT … ON CONFLICT
Learn how PostgreSQL’s INSERT … ON CONFLICT eliminates race‑prone SELECT‑then‑INSERT patterns by making upserts atomic and safe for concurrent workloads.
Prevent Lost Updates in Memcached with CAS Tokens
Use gets and cas to update shared memcached items safely without server-side locks.
memcachedWhen Your LabVIEW Queue-Based State Machine Hits a Wall: Choosing Actor Framework
Your queue-based LabVIEW architecture works — until it doesn't. Actor Framework adds structure for scaling concurrency, but brings boilerplate and versioning discipline. Here's how to decide if the trade-off pays off for your application.
PostgreSQL Upserts with INSERT ... ON CONFLICT: Atomic Insert-or-Update
Use INSERT ... ON CONFLICT to insert or update a row atomically when a unique constraint exists, and verify the result with the command tag.
Choosing Between Arc<Mutex<T>> and Arc<RwLock<T>> for Shared State
Learn when to use Arc<Mutex<T>> versus Arc<RwLock<T>> in Rust. This guide compares exclusive and shared access patterns, explores performance trade-offs, and provides a concrete implementation for shared state.
rustErlang gen_server: When the Synchronous Loop Becomes Your Bottleneck
Your gen_server serializes requests by design. Learn when that guarantee helps and when to refactor to async or multi-process patterns for throughput.
Elixir Task.async_stream: Bounded Concurrency for I/O-Bound Enumerables
Task.async_stream caps concurrent work on an enumerable, isolates per-item failures, and preserves order by default. Learn the trade-offs and how to verify behavior in your Elixir version.
