For remote logging with Elasticsearch, currently only reading log is supported. Users need to deploy other softwares (such as filebeat & logstash) to ship Airflow task logs to Elasticsearch. Also, user would need to ensure the log messages contain a valid log_id of format {dag_id}-{task_id}-{execution_date}-{try_number} in order for reading remote log to work.
This PR will enable the ElasticSearchTaskHandler to automatically write each task log to Elasticsearch after each DAG task is completed. 2 more config are introduced (namely:
write_to_esandtarget_index, which are set to False andairflow-logsby default`)The ElasticSearchTaskHandler will now also consider the config
delete_local_logsinloggingsession. When bothwrite_to_esanddelete_local_logsare set to True, the handler will delete local task logs upon successfully writing logs to ES.related: #42780
