This processor is used to create a Hadoop Sequence File, which essentially is a file of key/value pairs. The key
will be a file name and the value will be the flow file content. The processor will take either a merged (a.k.a. packaged) flow
file or a singular flow file. Historically, this processor handled the merging by type and size or time prior to creating a
SequenceFile output; it no longer does this. If creating a SequenceFile that contains multiple files of the same type is desired,
precede this processor with a RouteOnAttribute
processor to segregate files of the same type and follow that with a
MergeContent
processor to bundle up files. If the type of files is not important, just use the
MergeContent
processor. When using the MergeContent
processor, the following Merge Formats are
supported by this processor:
In the list below, the names of required properties appear in bold. Any other properties (not in bold) are considered optional. If a property has a default value, it is indicated. If a property supports the use of the NiFi Expression Language (or simply, "expression language"), that is also indicated.
