ACME uses different domain-control validation methods. tls-alpn-01 works on shared hosting without DNS access; DNS challenges suit wildcard certificates but require external DNS control.

Grab’s Iris project replaces a fragmented Spark observability stack with a centralised platform for real-time and historical analysis. The previous setup split data between Grafana, Superset, InfluxDB, and a data lake, creating usability, access-control, pipeline, metadata, and high-cardinality query challenges. The new architecture uses StarRocks as a unified store, ingesting Kafka directly, serving a custom Iris web application and Superset, and backing up to S3. Its relational data model links worker metrics through worker_uuid and Spark event metrics through app_id, while materialised views and dynamic partitioning support responsive queries and data retention as volumes grow. The resulting system consolidates metrics and metadata, simplifies ingestion and offline processing, and supports job-level showback/chargeback; the roadmap includes recommendations, advanced analytics, machine learning, and scalability improvements.
