Everything set up but while using kafka reciever it stucked at logs showing that —-> 2024-08-25T041734.167+0530  info  kafkareceiver/kafka_receiver.go:474  Starting consumer group  {"kind": "receiver", "name": "kafka", "data_type": "traces", "partition": 0} Below is my config yaml receivers: kafka: protocol_version: 2.0.0 topic: mykafka brokers:"localhost:9092" resolve_canonical_bootstrap_servers_only: true metadata: retry: max: 10 backoff: 5s otlp: protocols: http: endpoint: 0.0.0.0:4318 grpc: endpoint: 0.0.0.0:4317 kafka/logs: topic: mykafka session_timeout: 45s heartbeat_interval: 15s encoding: direct brokers:"localhost:9092" initial_offset: earliest metadata: retry: max: 10 backoff: 5s processors: batch: timeout: 5s send_batch_size: 100000 resource: attributes🔑 test.key value: "test-value" action: insert exporters: debug: verbosity: normal clickhouse: endpoint: tcp://127.0.0.1:9000?dial_timeout=10s database: otel async_insert: true ttl: 72h compress: lz4 create_schema: true logs_table_name: otel_logs traces_table_name: otel_traces metrics_table_name: otel_metrics timeout: 5s retry_on_failure: enabled: true initial_interval: 5s max_interval: 30s max_elapsed_time: 300s extensions: health_check: {} zpages: {} service: extensions: [zpages, health_check] pipelines: logs: receivers: [ kafka ] processors: [ batch ] exporters: [ clickhouse ] traces: receivers: [ kafka ] processors: [ batch ] exporters: [ clickhouse ] metrics: receivers: [ kafka ] processors: [ batch ] exporters: [ clickhouse ]
