[jira] [Commented] (AIRFLOW-1708) pass JSON through the DAG pipeline

    [ https://issues.apache.org/jira/browse/AIRFLOW-1708?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16202592#comment-16202592 ] 

Joy Gao commented on AIRFLOW-1708:
----------------------------------

That's correct, you can specific the param `task_ids` when you call xcom_pull. The goal of xcom is communication between tasks, so it serves the use case you described fairly well.

> Hello dear community,
> is it a right way to pass a JSON by means of xcom_push function in a task and also get the same JSON through xcom_pull in the next task? Or is there any other ways to do this?
> Thanks!
