[jira] [Resolved] (FLUME-998) JDBC Channel take does not block

     [ https://issues.apache.org/jira/browse/FLUME-998?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Brock Noland resolved FLUME-998.
--------------------------------

       Resolution: Won't Fix
    Fix Version/s:     (was: v1.1.0)

It has been decided the channels should not block but that the HDFSEventSink should return backoff when the channel has no events. Another JIRA will be submitted to fix this.

> Memory Channel takes block for a few seconds if there are no events to take. This so the thread consuming events does not spin in a tight loop. JDBC Channel does not block and returns null immediately, as such the thread gettings events spins hard.
