ASF GitHub Bot commented on NIFI-2850: -------------------------------------- Github user olegz commented on the issue: https://github.com/apache/nifi/pull/1115 @markap14 all is good. +1 here but think someone else should give it a look as well given its complexity. > Provide ability for a FlowFile to be migrated from one Process Session to > another > --------------------------------------------------------------------------------- > > Key: NIFI-2850 > URL: https://issues.apache.org/jira/browse/NIFI-2850 > Project: Apache NiFi > Issue Type: Improvement > Components: Core Framework > Reporter: Mark Payne > Assignee: Oleg Zhurakousky > Fix For: 1.1.0 > > > Currently, the MergeContent processor creates a separate ProcessSession for > each FlowFile that it pulls. This is done so that we can ensure that we can > commit all Process Sessions when a bin is full. Unfortunately, this means > that MergeContent is required to call ProcessSession.get() many times, which > adds a lot of contention on the FlowFile Queue. If we allow FlowFiles to be > migrated from 1 session to another, we can have a session per bin, and then > use ProcessSession.get(100) to greatly reduce lock contention. This will > likely have benefits in other processors as well. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
