- Redis overtakes MongoDB in popularity (based on https://db-engines.com/en/ranking).

- Apache Spark starts its relatively slow decline in favor of vendor and in-house solutions.

- Cost drives cloud systems away from managed solutions (think AWS Batch) towards semi-managed solutions (think self-run k8s deployments but on AWS EKS).

- There are no improvements in autoscaling k8s clusters.

- Integration testing is replaced by testing in the development environment.
