/**
 * Time Series Compression Manager
 *
 * Implements advanced compression algorithms optimized for time series data:
 * - Gorilla compression for floating-point values
 * - Delta-of-delta encoding for timestamps
 * - Dictionary compression for strings
 * - Generic algorithms (zstd, lz4, snappy)
 *
 * Features:
 * - Automatic algorithm selection based on data characteristics
 * - Streaming compression for real-time data
 * - Configurable compression levels
 * - Compression ratio monitoring
