Description:

Splits a binary encoded Avro datafile into smaller files based on the configured Output Size. The Output Strategy determines if the smaller files will be Avro datafiles, or bare Avro records with metadata in the FlowFile attributes. The output will always be binary encoded.

Properties:

In the list below, the names of required properties appear in bold. Any other properties (not in bold) are considered optional. The table also indicates any default values.

Name	Default Value	Allowable Values	Description
Split Strategy	Record	*Record	The strategy for splitting the incoming datafile. The Record strategy will read the incoming datafile by de-serializing each record.
Output Size	1		The number of Avro records to include per split file. In cases where the incoming file has less records than the Output Size, or when the total number of records does not divide evenly by the Output Size, it is possible to get a split file with less records.
Output Strategy	Datafile	*Datafile *Bare Record	Determines the format of the output. Either Avro Datafile, or bare record. Bare record output is only intended for use with systems that already require it, and shouldn't be needed for normal use.
Transfer Metadata	true	* true * false	Whether or not to transfer metadata from the parent datafile to the children. If the Output Strategy is Bare Record, then the metadata will be stored as FlowFile attributes, otherwise it will be in the Datafile header.

Relationships:

Name	Description
original	The original FlowFile that was split. If the FlowFile fails processing, nothing will be sent to this relationship
failure	If a FlowFile fails processing for any reason (for example, the FlowFile is not valid Avro), it will be routed to this relationship
split	All new files split from the original FlowFile will be routed to this relationship
