Properties¶

In the list below required Properties are shown with an asterisk (*). Other properties are considered optional. The table also indicates any default values, and whether a property supports the NiFi Expression Language.

Display Name	API Name	Default Value	Allowable Values	Description
Schema Access Strategy *	Schema Access Strategy	inherit-record-schema	Inherit Record Schema Use ‘Schema Name’ Property Use ‘Schema Text’ Property	Specifies how to obtain the schema that is to be used for interpreting the data.
Schema Branch	Schema Branch			Specifies the name of the branch to use when looking up the schema in the Schema Registry property. If the chosen Schema Registry does not support branching, this value will be ignored.
Schema Cache	Schema Cache			Specifies a Schema Cache to add the Record Schema to so that Record Readers can quickly lookup the schema.
Schema Name	Schema Name	${schema.name}		Specifies the name of the schema to lookup in the Schema Registry property
Schema Reference Reader *	Schema Reference Reader			Service implementation responsible for reading FlowFile attributes or content to determine the Schema Reference Identifier
Schema Reference Writer *	Schema Reference Writer			Service implementation responsible for writing FlowFile attributes or content header with Schema reference information
Schema Registry	Schema Registry			Specifies the Controller Service to use for the Schema Registry
Schema Text	Schema Text	${avro.schema}		The text of an Avro-formatted Schema
Schema Version	Schema Version			Specifies the version of the schema to lookup in the Schema Registry. If not specified then the latest version of the schema will be retrieved.
Schema Write Strategy *	Schema Write Strategy	avro-embedded	Embed Avro Schema Do Not Write Schema Set ‘schema.name’ Attribute Set ‘avro.schema’ Attribute Schema Reference Writer	Specifies how the schema for a Record should be added to the data.
Cache Size *	cache-size	1000		Specifies how many Schemas should be cached
Compression Format *	compression-format	NONE	BZIP2 DEFLATE NONE SNAPPY LZO	Compression type to use when writing Avro files. Default is None.
Encoder Pool Size *	encoder-pool-size	32		Avro Writers require the use of an Encoder. Creation of Encoders is expensive, but once created, they can be reused. This property controls the maximum number of Encoders that can be pooled and reused. Setting this value too small can result in degraded performance, but setting it higher can result in more heap being used. This property is ignored if the Avro Writer is configured with a Schema Write Strategy of ‘Embed Avro Schema’.
