Heka buffering problem

[DonHarishAxe]

Does the Heka tool have a common queue buffer for a plugin? I have set buffering to be true in my ESOutput plugin. I have two heka processes running simulatneously dumping data to different index in ElasticSearch. When one heka process stops due to an issue or an explicit pause, the second process takes up the data of the first process from the queue and dumps it into its index. Kindly help.
Thanks.
