Query Optimizer

Observability query acceleration and cost optimization

Overview

The Query Optimizer accelerates observability queries through intelligent query planning, result caching, federated execution, and cost-based optimization. Reduce query latency by 10-100x and costs by 50-90% without changing application code.

Features

Query Optimization

• Query planning — Generate optimal execution plans
• Index recommendations — Suggest indexes for faster queries
• Query rewriting — Transform queries for better performance
• Predicate pushdown — Filter data early
• Partition pruning — Query only relevant partitions

Caching

• Result caching — Cache query results with TTL
• Partial caching — Cache intermediate results
• Smart invalidation — Invalidate on data changes
• Multi-level caching — Memory, SSD, distributed

Federated Queries

• Cross-system queries — Query multiple backends
• Data federation — Unified query interface
• Parallel execution — Execute across multiple nodes

Quick Start

# config.yaml
optimizer:
  enabled: true
  
  caching:
    enabled: true
    ttl: 300s  # 5 minutes
    max_size: 10GB
  
  backends:
    - name: prometheus
      type: prometheus
      url: "http://prometheus:9090"
    
    - name: elasticsearch
      type: elasticsearch
      url: "http://elasticsearch:9200"

Optimize Query

from query_optimizer import QueryOptimizer

optimizer = QueryOptimizer(config_path="config.yaml")

# Original query
query = """
SELECT service, AVG(latency) 
FROM metrics 
WHERE timestamp > now() - 1h
GROUP BY service
"""

# Optimize
optimized = optimizer.optimize(query)
print(f"Estimated speedup: {optimized.speedup}x")
print(f"Cost reduction: {optimized.cost_reduction}%")

# Execute optimized query
result = optimized.execute()

Performance

• Query speedup: 10-100x
• Cost reduction: 50-90%
• Cache hit rate: > 80%
