How we made global routing faster with Bloom filters

Recently, we shipped an optimization to our global routing service that reduced its memory usage by 15%, improved time-to-first-byte (TTFB) from the 75th percentile and above by 10%, and significantly improved routing speeds for websites with many static paths. A small number of websites, with hundreds of thousands of static paths, were creating a bottleneck that slowed down our entire routing service. By replacing a slow JSON parsing operation with a Bloom filter, we brought path lookup latency

AI Search - New Metrics View in AutoRAG

AutoRAG now includes a Metrics tab that shows how your data is indexed and searched. Get a clear view of the health of your indexing pipeline, compare usage between ai-search and search, and see which files are retrieved most often. You can find these metrics within each AutoRAG instance: Indexing: Track how files are ingested and see status changes over time. Search breakdown: Compare usage between ai-search and search endpoints. Top file retrievals: Identify which files are most frequently re

Workers - Rate Limiting in Workers is now GA

Rate Limiting within Cloudflare Workers is now Generally Available (GA). The ratelimit binding is now stable and recommended for all production workloads. Existing deployments using the unsafe binding will continue to function to allow for a smooth transition. For more details, refer to Workers Rate Limiting documentation.

Workers - Panic Recovery for Rust Workers

In workers-rs, Rust panics were previously non-recoverable. A panic would put the Worker into an invalid state, and further function calls could result in memory overflows or exceptions. Now, when a panic occurs, in-flight requests will throw 500 errors, but the Worker will automatically and instantly recover for future requests. This ensures more reliable deployments. Automatic panic recovery is enabled for all new workers-rs deployments as of version 0.6.5, with no configuration required. Fixi
