RFC 10008 standardized the QUERY HTTP method in June 2026, the first new standard HTTP verb since PATCH in 2010. Debezium 3.6 is out with breaking changes across multiple connectors. AWS Certificate Manager now supports ACMEv2 for automated 45-day certificate issuance and renewal. --- ## Netflix dynamic Cassandra partition splitting drops read latency from seconds to low double-digit milliseconds Netflix built an automatic partition-splitting system for Apache Cassandra that detects oversized partitions and asynchronously splits them into smaller child partitions, with a metadata layer routing reads transparently — no application changes or downtime required. On their TimeSeries Abstraction platform, average read latency fell from seconds to low double-digit milliseconds, tail latencies dropped under 200ms, and CPU utilization and read timeouts both decreased. The initial implementation targets immutable partitions for safety, with mutable partition support and reprocessing of failed splits planned next. If you're running Cassandra for time-series workloads and hitting wide-partition pain, this is worth reading closely.

Unlike POST, QUERY is safe, idempotent, and cacheable — it never modifies server state and can be safely replayed. It also supports saving queries as reusable URIs. Practical adoption is expected around 2027-2028 as server and client implementations catch up, but it's worth factoring into API design decisions now.

MySQL drops the 'never' snapshot mode, Oracle deprecates the 'redo_log_catalog' mining strategy, PostgreSQL enum values now return in logical sort order, and MongoDB schema names shift for Avro compatibility. On the new features side: off-heap RocksDB-based schema history storage, quantile metrics across all connectors, a new Amazon SNS sink, JDBC sink as a native Debezium Server sink, an incubating Apache Fluss sink, a new YashanDB source connector, and OpenTelemetry support in the Debezium Platform. The Kafka-less pipeline path via JDBC sink in Debezium Server is also now documented with a full PostgreSQL-to-MySQL tutorial.

It works with Certbot, cert-manager for Kubernetes, and acme.sh out of the box. PKI administrators can define domain scopes, enforce wildcard policies, and delegate certificate requests to application teams without sharing DNS credentials — domain validation happens once at the endpoint level. Available in all commercial AWS regions now.
