The Lattice SDK now supports streaming entity updates in real-time using the REST API across all supported languages: * Added [`StreamEntities`](/reference/rest/entities/stream-entities) API for establishing persistent connections to stream entity events * Implemented examples for streaming entities in Go, Java, Python, and TypeScript * Updated documentation to demonstrate both basic streaming and component filtering ## New features The new `StreamEntities` API provides several configurable parameters: * **`preExistingOnly`**: Controls whether to stream only existing entities or include real-time updates. * **`heartbeatIntervalMS`**: Configures how frequently the server sends heartbeat events. * **`componentsToInclude`**: Allows filtering which entity components are streamed, reducing bandwidth usage and improving performance. ## Documentation updates As a part of this release, [Watch entities](/guides/entities/watch) guide has been updated with code examples in all supported languages. Each example demonstrates both basic entity streaming and filtering specific components, providing common patterns for integrating real-time entity data into your Lattice apps.
