💻 Usage Examples

Streaming Data with New Extensions

// Using the new streaming extensions
public async Task StreamDataAsync(IAsyncEnumerable<DataChunk> dataStream)
{
    await foreach (var chunk in dataStream.WithMemoryOptimization())
    {
        // Process streaming data efficiently
        await ProcessChunk(chunk);
    }
}

Enhanced Session Communication

// Using the new SendSessionMessages RPC call
var sessionMessages = new SessionMessagesRequest
{
    SessionId = "session-123",
    Messages = { message1, message2, message3 }
};

await jiroHubClient.SendSessionMessagesAsync(sessionMessages);

Performance Monitoring

// Using the new PerformanceAnalyzer
using var analyzer = new PerformanceAnalyzer("StreamingOperation");
await PerformStreamingOperation();
// Performance metrics automatically captured and logged

Paginated Log Retrieval

// Using the enhanced GetLogsRequest with offset
var logsRequest = new GetLogsRequest
{
    Count = 50,
    Offset = 100, // New offset parameter for pagination
    SessionId = "session-456"
};

var response = await GetLogsAsync(logsRequest);

🚀 Deployment

  • Version 1.2.0 has been built, tested, and is ready for deployment to NuGet.org
  • All tests pass on .NET 9.0 runtime with streaming scenarios validated
  • Package metadata updated with latest version information
  • Streaming performance benchmarked and optimized for production workloads

🔮 Future Considerations

  • Streaming capabilities lay the foundation for real-time collaborative features
  • Enhanced gRPC services enable more sophisticated inter-service communication
  • Performance monitoring tools provide insights for future optimization efforts

Note: This release significantly enhances the real-time capabilities of the Jiro ecosystem, enabling efficient data streaming, improved session management, and comprehensive performance monitoring. The streaming infrastructure opens up new possibilities for responsive, data-intensive applications built on the Jiro platform.
