This is my consumer
using System;using System.Threading;using System.Threading.Tasks;using Confluent.Kafka;using Microsoft.Extensions.Configuration;using Microsoft.Extensions.Hosting;using Microsoft.Extensions.Logging;using Newtonsoft.Json;namespace commons.Kafka;public abstract class KafkaConsumer<T> : BackgroundService where T : class{ private readonly IConsumer<string, string> _consumer; private readonly string _groupId; private readonly ILogger<KafkaConsumer<T>> _logger; protected KafkaConsumer(ILogger<KafkaConsumer<T>> logger, IConfigurationSection config, params string[] topics) { _logger = logger; _groupId = GetType().Name.ToKebabCase(); _consumer = new ConsumerBuilder<string, string>(new ConsumerConfig { BootstrapServers = config["Kafka:BootstrapServers"], GroupId = _groupId, AutoOffsetReset = AutoOffsetReset.Earliest }).Build(); _consumer.Subscribe(topics); } protected abstract Task ProcessMessageAsync(Headers headers, string key, T value); protected virtual async Task ConsumeAsync(CancellationToken stoppingToken) { try { var consumeResult = _consumer.Consume(stoppingToken); if (consumeResult != null) { _logger.LogInformation("{Consumer}: consumed {Key}", _groupId, consumeResult.Message.Key); if (Type.GetTypeCode(typeof(T)) != TypeCode.Object) { await ProcessMessageAsync(consumeResult.Message.Headers, consumeResult.Message.Key, consumeResult.Message.Value as T); } else { var value = JsonConvert.DeserializeObject<T>(consumeResult.Message.Value); await ProcessMessageAsync(consumeResult.Message.Headers, consumeResult.Message.Key, value); } } } catch (OperationCanceledException) { // Ignore cancellation exception } catch (Exception ex) { _logger.LogError(ex, "{Consumer}: Error consuming message", _groupId); } } protected override async Task ExecuteAsync(CancellationToken stoppingToken) { _logger.LogInformation("{Consumer}: starting", _groupId); stoppingToken.Register(() => { _logger.LogInformation("{Consumer}: stopping", _groupId); _consumer.Close(); }); // create a new process to consume messages while (!stoppingToken.IsCancellationRequested) await Task.Run(() => ConsumeAsync(stoppingToken), stoppingToken); _consumer.Close(); }}after recreating the topic, the consumer seems like frozen what happened?
