July 2024 Summaries

Batch Keys is a new feature that enhances Event Batching by allowing developers to group work units using Inngest's efficient event-matching engine. This feature addresses fairness issues, improves reliability, and simplifies the developer experience. By leveraging event properties, Batch Keys enables developers to configure batch composition for advanced use cases such as Batch User Notifications or more efficient processing of large volumes of events.

The article discusses how Inngest successfully sharded its high-throughput Redis database without any downtime. This was achieved by creating a new interface layer to coordinate interaction with the function state database, launching a state coordinator service, and implementing sharding in the production codebase. The sharding rollout strategy involved multiple stages affecting various customer segments, starting with free-tier users and ending with enterprise customers. The outcomes of this effort included 80% fewer timeouts during traffic peaks, lower CPU utilization, and a consistent latency drop from 35-50ms to 7ms.

The Summer PCXI Hackathon is a two-week event starting on July 5th, 2024, where participants can build fun projects using the PXCI stack and win cash and swag prizes. Teams of one or two people are allowed to participate, with submissions requiring the use of Xata, Clerk, Inngest, and Prisma's free tiers. The submitted apps will be judged based on their usage of the stack and UX, with extra points awarded for integrating AI, creating engaging content, and generating public engagement through promotional efforts on social networks. A PCXI starter project is available to help participants start building right away. Prizes include $2500 USD for first place, $1000 USD for second place, and $500 USD for third place, along with Xata & Partner Swag.
