Companion

Companion object for the RedisPromptCache class, functioning as a factory for creating Redis-backed implementations of the PromptCache interface.

This factory is identified by the name "redis" and is responsible for parsing a configuration string to initialize a RedisPromptCache instance with the specified properties such as Redis URI, cache key prefix, and cache expiration time-to-live (TTL).

The companion object extends the PromptCache.Factory.Named class to associate the factory with the specific name "redis" and implements the create method to generate instances of RedisPromptCache.

Constants:

• DEFAULT_URI: Default URI for connecting to Redis, used if no URI is provided in the configuration.

• CACHE_KEY_PREFIX: Default prefix for cache keys, used if no prefix is specified in the configuration.

Properties:

• logger: Logger instance for logging operations related to the RedisPromptCache.

Methods:

• create(config: String): Parses the provided configuration string to extract Redis URI, cache key prefix, and TTL, and returns a new RedisPromptCache instance initialized with these properties. Throws an exception if the cache type is not "redis".
