March 2026: Delivered EMF enrichment capabilities for metrics in the AWS SDK for Java v2 by extending EmfMetricLoggingPublisher with custom properties via PropertiesFactory. This enhancement improves CloudWatch Logs searchability and observability by enriching EMF records at publish time. Implemented supplier-based property provisioning, safe property resolution, and deterministic write order to ensure properties do not leak or collide with existing keys. Also added required configuration hooks, null-safety handling, collision filtering, and changelog updates. This work strengthens monitoring visibility, accelerates issue diagnosis, and contributes to more actionable telemetry.

Delivered a unified Spark Job base framework for AWS Glue Spark jobs by introducing a base SparkJob class and SparkJobProps to centralize handling of code-related arguments (extraJars, extraFiles, extraPythonFiles). This enables reuse across PySpark and Scala Spark jobs, reducing duplication and improving consistency and flexibility for Glue job configurations. This refactor lays the groundwork for faster onboarding of new Spark jobs and improves reliability across pipelines. Commit reference: 759e692c85511e7f00e5057a3d3dfd23a31e32eb (chore(glue-alpha): refactor spark jobs code-related props handling (#33567)).

February 2025 monthly summary: Delivered Kinesis Stream Consumer support with Lambda integration for the Tietew/aws-cdk project, introducing a new StreamConsumer construct, updating resource policy handling, and integrating Lambda event sources to enable fan-out consumption and cross-account access. This work enhances data processing efficiency, flexibility for downstream consumers, and aligns with cross-account security requirements. No major bugs fixed this month; minor policy-related issues were addressed to ensure robust deployment.
