Instance Method Summary

• #cache_fragment(fragment_name : String, params : Hash(String, DB::Any) = {} of String => DB::Any, tags : Array(String) = [] of String, ttl : Time::Span | Nil = nil, &block : -> String) : String | Nil

  Cache a fragment with automatic key generation

• #cache_query(sql : String, query_params : Array(DB::Any) = [] of DB::Any, cache_tags : Array(String) = [] of String, ttl : Time::Span = @config.default_ttl, &)

  Query fragment caching for database results

• #cache_with_key(cache_key : String, tags : Array(String) = [] of String, ttl : Time::Span = @config.default_ttl, &block : -> String) : String | Nil

  Cache with explicit key

• #delete_fragment(fragment_name : String, params : Hash(String, DB::Any) = {} of String => DB::Any) : Bool

  Delete a specific fragment

• #fragment_cached?(fragment_name : String, params : Hash(String, DB::Any) = {} of String => DB::Any) : Bool

  Check if a fragment is cached

• #generate_fragment_key(fragment_name : String, params : Hash(String, DB::Any) = {} of String => DB::Any) : String

  Generate cache key with consistent hashing

• #generate_query_key(sql : String, params : Array(DB::Any) = [] of DB::Any) : String

  Generate cache key for SQL queries

• #get_fragment(fragment_name : String, params : Hash(String, DB::Any) = {} of String => DB::Any) : String | Nil

  Get a cached fragment

• #invalidate_tags(tags : Array(String)) : Int32

  Invalidate fragments by tags

• #stats : Hash(String, String | Int32 | Int64 | Float64)

  Statistics about fragment cache usage
