Supercharge Your Hiero Hashgraph: Unleash the Power of the Block Stream Simulator
Want to supercharge your Hiero Hashgraph testing and development? The Block Stream Simulator is your answer. This guide dives deep into this powerful tool, showing you how to use it to simulate block streaming and unlock crucial insights. Prepare to boost your CTR by understanding how the simulator's features streamline your development process.
What is the Block Stream Simulator?
The Block Stream Simulator is designed to simulate block streaming specifically for the Hiero Hashgraph. It's built with a modular structure and uses dependency injection to manage its components effectively. This allows you to create realistic scenarios for performance, load, and stress testing.
Project Design Structure: Dagger2 and Modular Architecture
The core of the Block Stream Simulator lies in its well-organized structure. Here's what makes it tick:
- Dagger2 for Dependency Injection: Streamlines component management and enhances testability.
- Modular Design: Divides dependencies for better organization and maintainability.
- Centralized Injection Module: All modules converge at
src/java/com/hedera/block/simulator/BlockStreamSimulatorInjectionModule.java
.
How the Block Stream Simulator Works: The Entry Point
The entry point is BlockStreamSimulator.java and it has two key functions:
- Configuration Loading: Uses the Hiero Platform Configuration API for seamless setup.
- Dagger Component Creation: Instantiates the
BlockStreamSimulatorApp
class with registered dependencies.
The BlockStreamSimulatorApp orchestrates the simulation, managing streaming rates and exit conditions.
Key Services Consumed by the Block Stream Simulator
This app relies on injected services for its functionality:
- Block Generation (
generator
): TheBlockStreamManager
interface offers various implementations:BlockAsDirBlockStreamManager
: Generates blocks from a directory, each folder representing a block.BlockAsFileBlockStreamManager
: Creates blocks from a single file (CN recordings format), ideal for fast streaming tests.BlockAsFileLargeDataSets
: Designed for large datasets, perfect for performance and stress testing with significant block sizes and volumes.
- gRPC Communication (
grpc
): Handles communication with the Block-Node viaPublishStreamGrpcClient
andPublishStreamObserver
.
Configuration Options: Tailor Your Simulation
Refer to the Configuration documentation for the full array of customization settings. This enables you to precisely control your simulated environment.
