Struct CacheConfig 

pub struct CacheConfig {
    pub cache_type: String,
    pub memory_size: Option<usize>,
    pub redis_url: Option<String>,
    pub key_prefix: String,
    pub default_ttl: Option<u64>,
    pub crate_docs_ttl_secs: Option<u64>,
    pub item_docs_ttl_secs: Option<u64>,
    pub search_results_ttl_secs: Option<u64>,
}

Cache configuration

Configure cache type, size, TTL, and other parameters.

Fields

• cache_type: Cache type, "memory" or "redis"
• memory_size: Memory cache size(number of entries)
• redis_url: Redis connection URL
• key_prefix: Key prefix (used to isolate caches of different services)
• default_ttl: Default TTL (seconds)
• crate_docs_ttl_secs: Crate document cache TTL (seconds)
• item_docs_ttl_secs: Item document cache TTL (seconds)
• search_results_ttl_secs: Search result cache TTL (seconds)

Hot reload support

Hot reload supported fields ✅

TTL-related fields can be dynamically updated at runtime (affecting newly written cache entries):

• default_ttl: Default TTL (seconds)
• crate_docs_ttl_secs: Crate document cache TTL (seconds)
• item_docs_ttl_secs: Item document cache TTL (seconds)
• search_results_ttl_secs: Search result cache TTL (seconds)

Hot reload NOT supported fields ❌

The following fields require server restart to take effect:

• cache_type: Cache type (involves cache instance creation)
• memory_size: Memory cache size(initialization parameter)
• redis_url: Redis connection URL(connection pool initialization)
• key_prefix: Cache key prefix(initialization parameter)

Reason: These configurations involve initialization of cache backend (memory/Redis) and connection pool creation.

Fields

cache_type: String

Cache type: memory or redis

memory_size: Option<usize>

Memory cache size(number of entries)

redis_url: Option<String>

Redis connection URL

key_prefix: String

Redis cache key prefix (used to isolate caches of different services)

default_ttl: Option<u64>

Default TTL (seconds)

crate_docs_ttl_secs: Option<u64>

Crate document cache TTL (seconds)

item_docs_ttl_secs: Option<u64>

Item document cache TTL (seconds)

search_results_ttl_secs: Option<u64>

Search result cache TTL (seconds)
