August 2026 Summaries

Eternal Ltd., the India-based technology company behind Zomato, Blinkit, Hyperpure, and District, migrated latency-insensitive logging, analytics, and benchmarking workloads from self-hosted and managed Apache Kafka to WarpStream’s BYOC platform. Its previous self-hosted Kafka deployment was limited to one availability zone and minimal replication to control cloud networking costs, while managed Kafka also involved disk, interzone, and lengthy cluster-provisioning costs. Following a two-week proof of concept and two additional weeks to production, Eternal reported 60% savings for its logging infrastructure and 80% savings for benchmarking, while using S3-compatible object storage, avoiding replication and interzone charges, and automatically scaling for traffic ranging from 2.3 GiB/s to 25 GiB/s. WarpStream also reduced benchmarking-cluster creation from 20–30 minutes to seconds and enabled scale-to-zero during idle periods, supporting workloads averaging 52 million messages per minute during backfills. Eternal continues to use Confluent Cloud for latency-sensitive applications, directing workloads between platforms according to cost and performance requirements.
