[qy-liuhuo]

In order to more conveniently view the log output, using OpenTelemetry to achieve centralized log reporting

• Fixes [Feature][Sort] Provides a method to add openTelemetryAppender for the sort connector #11065

Motivation

In order to more conveniently view the sort task log, we need to achieve a centralized log reporting method.

Modifications

• Added some Maven dependencies related to openTelemetry at inlong-sort/sort-flink/base/pom.xml and pom.xml
• Designed and implemented an OpenTelemetryLogger class to add log reporting functionality for sort-connectors

  • Added integration tests for end-to-end deployment with large payloads (10MB)
  • Extended integration test for recovery after broker failure

Documentation

The way to integrate OpenTelemetryAppender for connectors that comply with the FLIP-27 standard is as follows:

1. Create a new OpenTelemetryLogger object in the corresponding SourceReader construction method and configure relevant parameters(log-collector endpoint，logLevel，layout and so on)
2. Call the install method of the openTelemetryLogger object in the start method of SourceReader
3. Call the uninstall method of the openTelemetryLogger object in the close method of SourceReader

[qy-liuhuo]

Just use it like this：

import org.apache.inlong.sort.base.util.OpenTelemetryLogger;

public class XXXSourceReader<T>
{

    private static final Logger LOG = LoggerFactory.getLogger(MySqlSourceReader.class);

    private final OpenTelemetryLogger openTelemetryLogger;

    public XXXSourceReader() {
        ...
        this.openTelemetryLogger = new OpenTelemetryLogger(); // initialize OpenTelemetryLogger
    }

    @Override
    public void start() {
        openTelemetryLogger.install(); // install OpenTelemetryLogger
        ...
    }

    @Override
    public void close() throws Exception {
        openTelemetryLogger.uninstall(); // uninstall OpenTelemetryLogger
        super.close();
    }
    
    ...
}

And you can configure the opentelemetryAppender by providing some parameters:

OpenTelemetryLogger(String serviceName, String endpoint, Layout<?> layout, Level logLevel)
