buildOne report1 publisher Iceberg 1.11.0 puts Spark, Flink and Hive file access behind one format registry
Iceberg 1.11.0 ships a File Format API that sends Spark, Flink, Hive and plain-Java reads and writes through one registry of format models. A dev.to walkthrough says the file format list stays fixed, so Vortex and Lance still need a change inside Iceberg.

Four-times-faster incident pipeline caught just 64% of in-scope incidents in a bad month
One SaaS team's rebuild of incident detection on Kafka and Flink cut telemetry lag from over 40 seconds to under 10, according to its CNCF post. Over eighteen months its recall ran from about 60% to 86% and back to 64%, so speed alone says little about which outages get caught.

buildOne report1 publisher Migrating from Dataflow to Flink includes installing cert-manager for the Kubernetes Operator
Apache Flink covers most of what Google's managed Dataflow does. A dev.to deployment guide prices the swap in prerequisites: cert-manager goes in before the operator, and the exactly-once path ends in a bucket whose keys you hold.

buildOne report1 publisher Collapsing three copies into one Iceberg table moves the conflict into an HTTP 409

buildOne report1 publisher Confluent triples its Kafka console ceiling to 400K partitions and leaves the brokers alone
Control Center 2.0 works against unchanged Confluent Platform 7.5 through 7.9 clusters. That compatibility line says the old limit was in the monitoring tier, not the data plane.

buildOne report1 publisher Iceberg won the table format war, then left the maintenance layer to you
The format ships compaction and expiry primitives without a scheduler. Netflix needed four internal services to cover that gap, and the arithmetic explains why.

buildOne report1 publisher Iceberg votes to forbid new equality deletes in V4, and Parquet 1.18.0 lands with two corruption bugs
Two decisions made on public mailing lists this week change what a safe lakehouse upgrade plan looks like. Streaming writers and anyone queued behind Parquet 1.18.0 need to re-read their notes.

buildOne report1 publisher Jumio's sub-100ms feature store is mostly a consistency build, not a speed build
AWS published the architecture behind Jumio's real-time feature store. Three of the four problems it starts from are about duplicated definitions and hand-copied code, not milliseconds.
