While RAW > transport protocol works fine with large files (I tested up to 8GB, but it > can be more), HTTP transport protocol starts failing if more than 2GB data is > sent at a time, meaning by sending a 2GB FlowFile, or batching multiple > FlowFiles to make more than 2GB into one transaction. > > When it fails, following log messages are written: > {code} > 2018-04-10 16:05:45,006 ERROR [I/O dispatcher 25] > o.a.n.r.util.SiteToSiteRestApiClient Failed to send data to > http://localhost:8080/nifi-api/data-transfer/input-ports/ad9a3887-0162-1000-e312-dee642179 > c9c/transactions/608f1ce4-56da-4899-9348-d2864e364d40/flow-files due to > java.lang.RuntimeException: Sending data to > http://localhost:8080/nifi-api/data-transfer/input-ports/ad9a3887-0162-1000-e312-dee > 642179c9c/transactions/608f1ce4-56da-4899-9348-d2864e364d40/flow-files has > reached to its end, but produced : read : wrote byte sizes (659704502 : > 659704502 : 9249639094) were not equal.
