Streaming de Eventos de Alto Rendimiento: Redis Streams y Consumer Groups en WRedis Día 10 de la Serie de Arquitectura Open Source de Wisrovi. Al construir arquitecturas distribuidas desacopladas, los equipos de ingeniería suelen enfrentarse a un dilema recurrente: Apache Kafka introduce una sobrecarga operativa considerable (JVM, ZooKeeper o KRaft, gestión de particiones en disco), mientras que el Pub/Sub clásico de Redis carece de persistencia (entrega at-most-once , pérdida de...

Maximize I/O throughput: Async/await consumers in Python Kafka. Day 10 of the WKafka Open-Source Engineering Series. Calling a slow external API inside a standard synchronous Kafka consumer is a recipe for missed heartbeats. WKafka supports async def natively. The Pain Points We Faced Sync network requests (HTTP, DB queries) freezing the Kafka consumer thread Missed broker heartbeats causing unwanted consumer group rebalance storms Expensive multi-process archite...

Maximiza el rendimiento I/O: Consumidores async/await en Kafka Python. Día 10 de la serie técnica WKafka Open Source. Llamar a una API externa lenta dentro de un consumidor síncrono estándar es garantía de perder heartbeats. WKafka soporta async def de forma nativa. Los Problemas Reales Llamadas de red síncronas bloqueando el hilo consumidor de Kafka Pérdida de heartbeats del broker provocando tormentas de rebalanceo Arquitecturas multi-proceso costosas para sopo...

Batching at scale: High-velocity bulk operations with insert_many. Inserting records in a for-loop is the number one performance mistake in SQLite development. wsqlite's insert_many groups thousands of records into a single atomic transaction for a 10x speedup. Here is how you use Bulk Insert & Batch Operations in production with wsqlite : from pydantic import BaseModel from wsqlite import WSQLite class Metric ( BaseModel ): id : int se...

Lotes a gran escala: Operaciones masivas de alta velocidad con insert_many. Insertar registros en un bucle for es el error de rendimiento número uno en SQLite. insert_many de wsqlite agrupa miles de registros en una sola transacción atómica multiplicando la velocidad por 10. Así se implementa Bulk Insert & Batch Operations en entornos reales con wsqlite : from pydantic import BaseModel from wsqlite import WSQLite class Metric ( BaseModel ): id ...

A healthtech catalog can generate several derivatives from one product photo. Storing every size indefinitely is a storage decision; generating one on every cache miss is a capacity decision. TL;DR: start with Sharp in your own service when image volume is predictable and you control the build. Choose hosted processing when native builds or batch throughput become the bigger operational burden. The hosted call removes a native dependency but adds a network hop. Neither choice makes cache design ...

Declarative blockchain security: The @master_audit and @slave_verify decorators. Day 10 of the wFabricSecurity Open-Source Engineering Series. Don't clutter your business logic with 30 lines of cryptographic validation code. wFabricSecurity @master_audit and @slave_verify decorators turn security into a single declarative line. The Pain Points We Faced Writing 30 lines of signature verification try/except logic inside every worker function Developers forgetting to ...

Sub-millisecond analytical APIs: Async ClickHouse for FastAPI. Day 10 of the WClickHouse Open-Source Engineering Series. Don't let analytical database queries block your web server. WClickHouse async client delivers non-blocking, sub-millisecond concurrency for modern Python APIs. The Pain Points We Faced Synchronous ClickHouse queries blocking the main asyncio thread in FastAPI API latency degrading when handling multiple concurrent dashboard requests Worker thr...

If AI can solve Navier Stokes grade problems, it should take a stab at such a thing too. I know the language is fundamentally not "english" or another widely used one so it can't do any inference on it but worth an experiment.

There are a number of places where I think AI provides leverage: logical code search, design brainstorming, investigation assistance, and so on. These are generally things where there is some amount of manual effort being offloaded and I can verify that the result is valid quickly. However, when it comes to design documents (writing) and implementation (coding), I seem to be in the minority that finds AI slowing me down. I think this is a problem with how I use it. For example, I always review t...
