Introduction
Thanos 0.28, released on November 5, 2022, continues to evolve as the leading solution for highly available, long-term Prometheus deployments. This release improves query performance, enhances storage integration, and delivers better multi-cluster support for enterprise-scale observability.
In practice, this release is most relevant when you’re running Kubernetes workloads at scale and your observability stack has to keep up—high-cardinality metrics, noisy alerts, and dashboards that need to stay responsive during incidents.
Query Performance Improvements
- Query engine optimizations reduce latency for queries across large time ranges.
- Caching enhancements improve response times for frequently accessed metrics.
- Parallel querying enables faster aggregation across multiple Prometheus instances.
- Memory management improvements reduce resource usage during query execution.
Storage Integration
- Object storage improvements provide better integration with S3, GCS, and Azure Blob Storage.
- Compaction enhancements reduce storage requirements and improve query performance.
- Retention policies enable more flexible data lifecycle management.
- Backup and restore improvements simplify disaster recovery procedures.
Multi-Cluster Support
- Global querying enables querying metrics across multiple Kubernetes clusters.
- Federation improvements simplify aggregating metrics from distributed Prometheus instances.
- Service discovery enhancements automatically discover Prometheus instances across clusters.
- Load balancing provides better distribution of query load across instances.
Operational Features
- Deployment simplifications make it easier to deploy and manage Thanos components.
- Monitoring expansion includes better metrics for Thanos component health.
- Documentation improvements provide clearer guides for common scenarios.
- Community growth demonstrates active development and adoption.
