Hi Koji, Actually i have set all connections to FIFO and concurrency tasks to 1 for all processors. Before and after the MergeRecord, I add a LogAttribute to debug. Before MergeRecord,the order in logfile is A,B,C in three flowfile After MergeRecord, the order becomes {A,C,B} in one flowfile

Hi Lei, How about setting FIFO prioritizer at all the preceding connections before the MergeRecord? Without setting any prioritizer, FlowFile ordering is nondeterministic. Thanks, Koji On Tue, Oct 15, 2019 at 8:56 PM wangl...@geekplus.com.cn wrote: > > > If FlowFile A, B, C enter the

MergeRecord can not guarantee the ordering of the input sequence?

If FlowFile A, B, C enter the MergeRecord sequentially, the output should be one FlowFile {A, B, C} However, when testing with large data volume, sometimes the output order will be not the same as they enter. And this result is nondeterministic This really confuses me a lot. Anybody has any
