Subject [jira] [Updated] (FLINK-10047) Checkpointing takes much longer with credit base flow control.
Date Fri, 03 Aug 2018 10:13:00 GMT

     [ https://issues.apache.org/jira/browse/FLINK-10047?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Piotr Nowojski updated FLINK-10047:
-----------------------------------
    Description: 
As reported by an user, in some scenario it looks like checkpointing takes significantly
more time (~40 minutes compared to ~2 minutes in Flink 1.4). Probably throughput is also lower.

We are waiting for more logs to get more details.
