Vector

by Datadog

High-performance, open-source observability data pipeline written in Rust — APAC platform and SRE teams use Vector to collect logs, metrics, and traces from APAC infrastructure, transform and enrich telemetry using Vector Remap Language (VRL), and route APAC observability data to multiple destinations (Elasticsearch, Datadog, S3, ClickHouse) with significantly lower resource consumption than JVM-based APAC log shippers.

"High-performance observability data pipeline from Datadog — APAC platform teams use Vector to collect APAC logs and metrics, transform telemetry with VRL (Vector Remap Language), and route APAC observability data to multiple backends with sub-millisecond processing latency."

What it does

Key features

  • VRL transforms — type-safe APAC log parsing and enrichment language
  • Multi-source — APAC files, Kafka, Kubernetes, syslog, HTTP sources
  • Multi-sink — Elasticsearch, Loki, Datadog, S3, ClickHouse APAC routing
  • Rust performance — low APAC resource usage at high APAC event throughput
  • Kubernetes enrichment — APAC pod metadata automatic annotation
  • Aggregations — APAC metrics computation from APAC log streams
When to reach for it

Best for

  • APAC platform teams replacing Logstash — Vector provides 10-100x APAC throughput improvement at 3-10x lower APAC memory cost; APAC teams paying for Logstash JVM heap tuning benefit immediately
  • APAC teams with complex APAC log transformation requirements — VRL's type-safe expression language handles APAC PII masking, APAC structured log extraction, and APAC multi-format normalization more expressively than Fluentd filters
  • APAC multi-destination telemetry routing — Vector's APAC fan-out routing sends the same APAC log stream to Loki (APAC debugging) and S3 (APAC long-term compliance archive) simultaneously without APAC stream duplication
Don't get burned

Limitations to know

  • ! APAC Datadog stewardship — Vector is open-source but maintained by Datadog; APAC teams concerned about APAC vendor direction should evaluate the APAC community contribution trajectory and APAC alternative (Fluent Bit)
  • ! APAC VRL learning curve — VRL is more powerful than Fluentd filter syntax but requires APAC learning investment; APAC teams with simple APAC log routing don't need VRL's expressiveness
  • ! APAC trace support is newer — Vector's APAC trace handling (OTLP ingestion) is less mature than its APAC log/metric pipeline; APAC teams with APAC trace-primary requirements may prefer OTel Collector
Context

About Vector

Vector is an open-source, high-performance observability data pipeline written in Rust that provides APAC platform and SRE teams a unified APAC log, metric, and trace collection, transformation, and routing component — where APAC teams configure Vector sources (APAC file logs, Kubernetes pod logs, host metrics, Kafka, APAC HTTP), apply VRL transformation functions (APAC log parsing, field extraction, enrichment from APAC lookup tables), and route processed APAC telemetry to multiple sinks (Elasticsearch, Loki, Datadog, S3, ClickHouse) in a single APAC pipeline definition.

Vector's VRL (Vector Remap Language) — where APAC platform teams write APAC log transformation logic in VRL's type-safe expression language (parsing APAC nginx access logs into structured fields, extracting APAC payment amounts from APAC event logs, masking APAC PII data like card numbers before routing to APAC external sinks) — provides APAC teams expressive APAC log transformation without the heavyweight scripting of APAC Logstash pipelines or the limited APAC transformation capability of Fluentd filter plugins.

Vector's performance characteristics — where APAC benchmarks show Vector processing APAC log data at 10-100x the throughput of APAC Logstash with 3-10x lower memory consumption, making Vector suitable for APAC high-volume log environments (APAC financial transaction logs at 100K+ events/second) without the APAC JVM heap tuning overhead of Logstash or the APAC Ruby GIL limitations of Fluentd — provides APAC platform teams APAC telemetry pipeline capacity without proportional APAC infrastructure cost.

Vector's APAC Kubernetes integration — where APAC platform teams deploy Vector as a DaemonSet to collect APAC Kubernetes pod logs from node filesystem, enrich APAC log events with Kubernetes metadata (APAC pod name, namespace, labels) via the Kubernetes enrichment transform, and route APAC pod logs to per-namespace Loki streams or APAC centralized Elasticsearch indices — provides APAC platform teams Kubernetes-native APAC log routing with metadata enrichment without APAC custom log parsing scripts.
