# CognitionAcp.ReplayBatchSupportMeta

> — client capability flag indicating that the client accepts extension notifications during / replay: one notification carrying several params in order.

`cognition.ai/replayBatch` — client capability flag indicating that the
client accepts `_cognition.ai/session_update_batch` extension
notifications during `session/load` / `session/resume` replay: one
notification carrying several `session/update` params in `id` order.
When absent or `false`, the proxy sends each replayed update as its own
`session/update` notification.

```typescript
type ReplayBatchSupportMeta = void
```
