clear

Example:

cache = RedisCache(
    redis_url="redis://localhost:6379",
    prefix="my_cache"
)

# Add some entries to the cache
cache.update("prompt1", "llm1", [Generation(text="Result 1")])
cache.update("prompt2", "llm2", [Generation(text="Result 2")])

# Clear all entries
cache.clear()

# After this, all entries with keys starting with "my_cache:"
# will be removed

Note:

• This method uses Redis SCAN to iterate over keys, which is safe for large datasets.
• It deletes keys in batches of 100 to optimize performance.
• Only keys that start with the specified prefix (default is 'redis:') will be deleted.
• This operation is irreversible. Make sure you want to clear all cached data before calling this method.
• If no keys match the prefix, the method will complete without any errors.
