# SelfManagedMemoryStrategy

Use AgentCore memory for event storage with custom triggers.

Define memory processing logic in your own environment.

Extends: SelfManagedMemoryStrategy
Implements: IMemoryStrategy

- Source: [`lib/memory/strategies/self-managed-strategy.ts`](https://github.com/aws/aws-cdk/blob/v2.275.0-alpha.0/packages/@aws-cdk/aws-bedrock-agentcore-alpha/lib/memory/strategies/self-managed-strategy.ts#L153)

## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as bedrock_agentcore_alpha from '@aws-cdk/aws-bedrock-agentcore-alpha';
import * as cdk from 'aws-cdk-lib';
import { aws_sns as sns } from 'aws-cdk-lib';

declare const topic: sns.Topic;
const selfManagedMemoryStrategy = new bedrock_agentcore_alpha.SelfManagedMemoryStrategy(bedrock_agentcore_alpha.MemoryStrategyType.SUMMARIZATION, {
  invocationConfiguration: {
    s3Location: {
      bucketName: 'bucketName',
      objectKey: 'objectKey',

      // the properties below are optional
      objectVersion: 'objectVersion',
    },
    topic: topic,
  },
  name: 'name',

  // the properties below are optional
  description: 'description',
  historicalContextWindowSize: 123,
  triggerConditions: {
    messageBasedTrigger: 123,
    timeBasedTrigger: cdk.Duration.minutes(30),
    tokenBasedTrigger: 123,
  },
});
```
