FFI for Rust and C# in ScyllaDB
FFI for Rust and C# in ScyllaDB: how we built an async bridge, avoided hidden marshalling errors, and maintained low latency.
API
API on ThecoreGrid covers production-grade API architecture for scalable, reliable, and secure systems.
We analyze how to design and evolve REST, gRPC, GraphQL, and event-driven interfaces in highload environments, with clear contracts, versioning strategies, and backward compatibility. The focus is on real engineering practice: API gateways, rate limiting, idempotency, retries, timeouts, circuit breakers, authN/authZ, and zero-trust patterns. You’ll find deep dives into performance tuning, caching, pagination, schema governance, observability, SLO/SLI design, and incident post-mortems from BigTech-level systems. Instead of basic tutorials, we provide architectural trade-offs and implementation patterns for distributed platforms, microservices, and cloud-native infrastructure. The API tag is built for backend engineers, platform teams, architects, and SREs who need maintainable interfaces, predictable reliability, and smooth evolution at scale across teams and services.
Distributed ad serving with low latency
Distributed ad serving in streaming: how to fit within 100 ms while balancing latency, personalization, and system resilience
Case folding without branching at memory speed
How to accelerate case folding to memory limits: an analysis of branchless loops, SIMD, and trade-offs in high-load code search
Cloudflare Workers Scales cdnjs to 9 Billion
Cloudflare Workers and R2 have become the foundation for cdnjs. The architecture handles 9 billion requests per day and changes the approach to CDN pipelines. The cdnjs system has hit a wall not in delivery, but in evolution. With 108,000 requests per second and a 98.6% cache hit rate, the delivery layer operated stably. Degradation … Read more
DNS routing for gRPC eliminates thundering herd
DNS routing for gRPC: how changing the Route 53 policy eliminated the thundering herd and distributed the load across 121 million connections without errors
WebRTC routing reduces latency in voice AI
WebRTC routing is becoming critical for voice AI, where audio stream continuity and minimal latency are essential. We analyze how the reworking of routing changes system behavior under load. The problem does not manifest immediately — until the moment the system scales to global real-time traffic. In the classic WebRTC model of “one port per … Read more
HSM vault for E2E backup without trust in the platform
HSM backup vault enhances end-to-end encryption for backups. The architecture eliminates platform access to keys and introduces verifiable trust. The problem arises when backups leave the device and enter the cloud. Even with end-to-end encryption, the question remains: who controls the recovery keys and how can it be proven that the provider does not have … Read more
Edge error handling without root cause data
Edge error handling without diagnostics breaks observability. An analysis of why errors without context block analysis and how this is addressed.
API Design and Data Architecture Without Hidden Failures
API design and data architecture: how to avoid system degradation, choose the right approach, and maintain consistency during scaling
Rate limiting breaks without input data
Rate limiting without data breaks architectural analysis. We examine why the lack of observability makes optimization impossible.
