## Quick Start

### Prerequisites

- Java 21 or higher
- OpenSearch/Elasticsearch cluster (2.x+ recommended)
- Maven 3.8+ for building from source

### Installation

Add the dependency to your `pom.xml`:

```xml
<dependency>

    super(threadName);
    this.lockLikeObject = checkNotNull(lockLikeObject);
    start();
  }
