CleverCloud/stream-dns

Stream-DNS is a DNS resolution service that consumes records from Kafka topics and stores them in a local BoltDB database. It provides core DNS query handling with CNAME recursion, alongside an HTTP administrator interface for record management. The system also includes a metrics collection agent that aggregates and batches observations for export to various outputs like StatsD and Warp10.

New utility functions have been added to support domain and DNS record handling. This includes helpers to detect apex domains and subdomains, extract query names and types from consumer keys, format DNS answers for logging, and manage trailing dots in domain names. A simple integer Min function was also added to complement the standard library.

utils · high confidence

This change introduces the initial open-source release of Stream-DNS, a DNS server that resolves queries by consuming records from Kafka topics and storing them in a local BoltDB database. The release includes the core DNS resolution logic with CNAME recursion support, a Kafka consumer with SASL/SCRAM authentication, and an HTTP administrator service for searching records (protected by JWT authentication). It also adds configuration via environment variables, Docker and Docker Compose support for local development, and comprehensive unit tests for the DNS handler and administrator endpoints.

This change adds the foundational \metrics\ package, defining the \Metric\ interface and its internal implementation to represent system observations. It supports two metric types, Counter and Gauge, and allows metrics to carry arbitrary tags, timestamps, and values. The implementation includes logic for serializing metrics to strings, ensuring tag uniqueness, and formatting output with UTC timestamps, providing the necessary data structures for downstream aggregation and reporting.

metrics · high confidence

The agent package now provides a metrics collection system that aggregates incoming counter and gauge metrics and flushes them to configured outputs in batches. The MetricsService manages aggregators, which buffer values and emit consolidated metrics at a configurable flush interval. The Agent component collects these metrics into a buffer and sends them to outputs either when the buffer reaches a configured size or when a timeout occurs, ensuring efficient batched transmission.

Added three new command-line utilities in the tools directory: a DNS lookup client (tools/client/client.go) that supports querying multiple questions in a single invocation; a Kafka producer (tools/producer/producer.go) for registering custom DNS records with metadata to a local Kafka node; and a seed script (tools/seed/seed.go) for populating Kafka topics with initial DNS record data using environment variables for configuration.

tools · high confidence

The application now supports sending metrics to multiple destinations via a new extensible output interface. Users can now export metrics to StatsD (with InfluxDB-style tag support), print them to stdout for development, or send them to Warp10 (configured via the WARP10\_WRITE\_TOKEN environment variable). This change introduces the underlying architecture for these outputs, including the StatsD client integration and the Warp10 client setup, while stdout remains available for debugging.

output · high confidence

The systemd unit file has been renamed from kafka-dns to stream-dns, updating the service description, executable path, and environment file reference to align with the new naming convention.

data · high confidence

The project now includes a go.mod file and a generated go.sum file, establishing the module name as stream-dns and defining its dependencies on Go 1.12. This manifest pins specific versions for key libraries including the Kafka client (Shopify/sarama v1.23.0, segmentio/kafka-go v0.3.3), the DNS resolver (miekg/dns v1.1.15, domainr/dnsr v0.0.0-20191026), and configuration tools (spf13/viper v1.4.0).
