to a larger AWS instance size, from m5.4xl (16 vCPUs) to m5.12xl (48 vCPUs). A quick canary test was free of errors and showed lower latency, which is expected given that our standard canary setup routes an equal amount of traffic to both the baseline running on 4xl and the canary on 12xl. let’s call it GS2?—?to

In particular, he talked about the misattribution potential in a complex microservice architecture where often intermediary results are cached. For example, a ranking team would ingest live user traffic and subject it to a number of ranking configurations and simulate the event outcomes using predictive models running on canary rankers.

The GraphQL shim enabled client engineers to move quickly onto GraphQL, figure out client-side concerns like cache normalization, experiment with different GraphQL clients, and investigate client performance without being blocked by server-side migrations. The Replay Tester tool samples raw traffic streams from Mantis.

I was a little restricted in my thinking the first time around and I’ve come to see FaaS as something not quite stateless, since caching state in a Lambda instance that might stick around for 5 hours is a perfectly reasonable idea. and products like AWS Fargate have made this distinction murkier still. Because of course it did.

It increases our visibility and enables us to draw a steady stream of organic (or “free”) traffic to our site. While paid marketing strategies like Google Ads play a part in our approach as well, enhancing our organic traffic remains a major priority. The higher our organic traffic, the more profitable we become as a company.

In databases like MySQL and PostgreSQL, transaction logs are the source of CDC events. Some of DBLog’s features are: Processes captured log events in-order. Interleaves log with dump events, by taking dumps in chunks. No locks on tables are ever acquired, which prevent impacting write traffic on the source database.
