1. #643: ConnectionClosingInterceptor interceptor closes connections that exceed
   a specified maximum lifetime age (TTL). It's beneficial for scenarios where your application requires establishing new connections to the same host after
   a predetermined interval.

The connection to the InfluxDB Enterprise with the ConnectionClosingInterceptor can be configured as follows:

package example;

import java.time.Duration;
import java.util.Collections;

import okhttp3.OkHttpClient;
import okhttp3.Protocol;

import com.influxdb.client.InfluxDBClient;
import com.influxdb.client.InfluxDBClientFactory;
import com.influxdb.client.InfluxDBClientOptions;
import com.influxdb.client.domain.WriteConsistency;
import com.influxdb.rest.ConnectionClosingInterceptor;

public class InfluxQLExample {

    public static void main(final String[] args) throws InterruptedException {

        //
        // Credentials to connect to InfluxDB Enterprise
        //
        String url = "https://localhost:8086";
        String username = "admin";
        String password = "password";
        String database = "database";
        WriteConsistency consistency = WriteConsistency.ALL;

        //
        // Configure underlying HTTP client
        //
        OkHttpClient.Builder okHttpClientBuilder = new OkHttpClient.Builder()
                .protocols(Collections.singletonList(Protocol.HTTP_1_1));

        //
        // Use new Connection TTL feature
        //
        Duration connectionMaxAge = Duration.ofMinutes(1);
        ConnectionClosingInterceptor interceptor = new ConnectionClosingInterceptor(connectionMaxAge);
        okHttpClientBuilder
                .addNetworkInterceptor(interceptor)
                .eventListenerFactory(call -> interceptor);

        //
        // Configure InfluxDB client
        //
        InfluxDBClientOptions.Builder optionsBuilder = InfluxDBClientOptions.builder()
                .url(url)
                .org("-")
                .authenticateToken(String.format("%s:%s", username, password).toCharArray())
                .bucket(String.format("%s/%s", database, ""))
                .consistency(consistency)
                .okHttpClient(okHttpClientBuilder);

        //
        // Create client and write data
        //
        try (InfluxDBClient client = InfluxDBClientFactory.create(optionsBuilder.build())) {

            // ...
        }
    }
}
