<strong>Zalando Engineering Blog - Why We Ditched Flink Table API Joins: Cutting State by 75% with DataStream Unions (6 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Zalando engineers slashed their Apache Flink application state size by 75% (from 240GB to 56GB) by ditching Flink SQL's Table API in favor of a custom DataStream API solution that consolidated four chained joins into a single operator. The team's custom MultiStreamJoinProcessor approach cut snapshot times and restart durations dramatically while reducing AWS costs by 13%, though they noted that Flink 2.1's new experimental Multi-Way Join Operator would eventually address similar state amplification issues they encountered in Flink 1.20.

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Google Cloud's Unified Maintenance is a centralized dashboard that lets users view and manage planned maintenance events across multiple services, including Compute Engine, GKE, Cloud SQL, Memorystore, AlloyDB, and Looker from a single interface. The new tool provides standardized alerts through Cloud Logging and clearly indicates which maintenance events offer user controls. Google plans to expand support to more services and add folder and organization-level visibility.

<strong>Run Pulumi Insights on Your Own Infrastructure (2 minute read)</strong>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Pulumi launched customer-managed workflow runners for Pulumi Insights, allowing enterprises to run cloud discovery scans and policy compliance checks on their own infrastructure rather than Pulumi-hosted systems to meet data residency and regulatory requirements. The lightweight agents work with both SaaS and self-hosted Pulumi Cloud installations, polling for tasks over HTTPS without requiring inbound network connectivity, and can use existing runner pools already deployed for Pulumi Deployments.
