class aws_cdk.aws_bedrockagentcore.SelfManagedStrategyProps(*, strategy_name, description=None, invocation_configuration, historical_context_window_size=None, trigger_conditions=None)

Bases: MemoryStrategyCommonProps

Configuration parameters for a self managed memory strategy existing built-in default prompts/models.

Parameters:

  • strategy_name (str) – The name for the strategy.

  • description (Optional[str]) – The description of the strategy. Default: - No description

  • invocation_configuration (Union[InvocationConfiguration, Dict[str, Any]]) – Invocation configuration for self managed memory strategy.

  • historical_context_window_size (Union[int, float, None]) – Define the number of previous events to be included when processing memory. A larger history window provides more context from past conversations. Default: 4

  • trigger_conditions (Union[TriggerConditions, Dict[str, Any], None]) – Trigger conditions for self managed memory strategy. Default: - undefined
