# NNTP Caching Proxy Configuration

# Cache configuration
[cache]
# Maximum memory cache size (default: 64mb)
# Supports human-readable formats: "1gb", "500mb", "64mb"
# For availability-only mode: ~1000 bytes per article
# For full caching: depends on article sizes (avg ~700 KB)

# Enable adaptive prechecking for STAT/HEAD commands (default: false)
# Queries all backends simultaneously to build availability data

# Disk Cache Configuration (optional)
# When configured, creates two-tier cache: memory -> disk -> backend
# Articles evicted from memory are written to disk for later retrieval
#
# [cache.disk]
# # Path to disk cache directory (will be created if needed)
# # Recommended: Use a fast SSD or NVMe drive

# # Supports: "100gb", "10gb", "1tb", or raw bytes
# capacity = "10gb"

# # Reduces disk usage by ~60% for typical NNTP articles
# compression = true
# # Number of shards for concurrent disk access (default: 4)
# # Higher values improve concurrency but use more file handles
