PROFILE
Andrey Zheltovskiy
Andrey Zheltovskiy contributed to the DataDog/datadog-agent repository by delivering five backend features over three months, focusing on scalable telemetry and configuration management. He implemented configurable batching for the OTLP ingest endpoint, allowing operators to fine-tune log and metric ingestion for improved throughput and resource efficiency. Andrey introduced environment-variable toggles for gateway metrics, enhancing operational visibility and safer rollouts. He also added Canonical Cloud Resource ID support to host metadata, enabling cross-cloud traceability, and refined gateway telemetry metrics for more accurate multi-pipeline reporting. His work, primarily in Go, demonstrated depth in API development, metrics management, and robust backend engineering practices.

Jan 1, 2026January 2026 (2026-01) performance summary for DataDog/datadog-agent. Focused on delivering cross-cloud observability, more reliable telemetry, and cost-conscious trace processing. Key features delivered: - Canonical Cloud Resource ID (CCRID) support in host metadata: Adds CCRID to host metadata and provides a retrieval pathway from resource attributes, enabling cross-cloud traceability across environments. Impact: unified resource tracing across clouds and environments. - Gateway Telemetry Metrics Enhancement: Improves detection and emission of gateway telemetry metrics across pipelines; refines metric instantiation and updates so the collector’s operational mode accurately reflects traffic from multiple pipelines. Impact: more accurate, actionable telemetry for capacity planning and alerting. - Infra-Attribute-Processor Toggle for OTLP Traces: Adds a configuration option to enable/disable the Infra-Attribute-Processor for traces in the OTLP ingest pipeline, enabling better control over trace data processing and potential cost savings for clients. Impact: operational flexibility and cost optimization. Major bugs fixed: - Fixed gateway telemetry detection to cover all pipelines, improving reliability of telemetry metrics collection across multiple pipelines. Impact: reduces misreporting and improves diagnosability. Overall impact and accomplishments: - Enhanced cross-cloud observability and traceability, more robust telemetry across pipelines, and configurable, cost-aware trace processing. These changes deliver measurable business value by improving diagnostics, cloud-agnostic reporting, and performance tuning for large-scale deployments. Technologies/skills demonstrated: - OTLP ingest pipelines, host metadata schema extension, CCRID integration, telemetry metric instrumentation, multi-pipeline detection logic, and configuration toggles for data processing. Commit references (examples): CCRID: 7feccf532cd912047ac170faed6e13034d0f8f23; GW telemetry fix: e6046ed001c7efcda06748d129e8a1b55d69a87f; OTLP infra-attr toggle: 928400dcee2f2d9196d2fbaefdeb1cf8ab79a612

Nov 1, 2025November 2025 monthly summary for DataDog/datadog-agent: Delivered configurable batching for the OTLP ingest endpoint, enabling batch parameters (min_size, max_size, and flush_timeout) for logs and metrics. This feature aligns with OTAGENT-636 and the associated commit, improving ingestion throughput and resource utilization while enabling production tuning. No major bugs reported this month; the focus was on feature delivery, code quality, and expanding the scalability of the OTLP ingestion pipeline. Business impact includes more predictable latency and better support for large-scale deployments by allowing operators to fine-tune batching behavior.
