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
CSV Format *	CSV Format	custom	Custom Format RFC 4180 Microsoft Excel Tab-Delimited MySQL Format Informix Unload Informix Unload Escape Disabled	Specifies which “format” the CSV data is in, or specifies if custom formatting should be used.
Character Set *	Character Set	UTF-8		The Character Encoding that is used to encode/decode the CSV file
Comment Marker	Comment Marker			The character that is used to denote the start of a comment. Any line that begins with this comment will be ignored.
Date Format	Date Format			Specifies the format to use when reading/writing Date fields. If not specified, Date fields will be assumed to be number of milliseconds since epoch (Midnight, Jan 1, 1970 GMT). If specified, the value must match the Java java.time.format.DateTimeFormatter format (for example, MM/dd/yyyy for a two-digit month, followed by a two-digit day, followed by a four-digit year, all separated by ‘/’ characters, as in 01/01/2017).
Escape Character *	Escape Character			The character that is used to escape characters that would otherwise have a specific meaning to the CSV Parser. If the property has been specified via Expression Language but the expression gets evaluated to an invalid Escape Character at runtime, then it will be skipped and the default Escape Character will be used. Setting it to an empty string means no escape character should be used.
Include Header Line *	Include Header Line	true	true false	Specifies whether or not the CSV column names should be written out as the first line.
Include Trailing Delimiter *	Include Trailing Delimiter	false	true false	If true, a trailing delimiter will be added to each CSV Record that is written. If false, the trailing delimiter will be omitted.
Null String	Null String			Specifies a String that, if present as a value in the CSV, should be considered a null field instead of using the literal value.
Quote Character *	Quote Character	“		The character that is used to quote values so that escape characters do not have to be used. If the property has been specified via Expression Language but the expression gets evaluated to an invalid Quote Character at runtime, then it will be skipped and the default Quote Character will be used.
Quote Mode *	Quote Mode	MINIMAL	Quote All Values Quote Minimal Quote Non-Numeric Values Do Not Quote Values	Specifies how fields should be quoted when they are written
Record Separator *	Record Separator	n		Specifies the characters to use in order to separate CSV Records
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	no-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.
Time Format	Time Format			Specifies the format to use when reading/writing Time fields. If not specified, Time fields will be assumed to be number of milliseconds since epoch (Midnight, Jan 1, 1970 GMT). If specified, the value must match the Java java.time.format.DateTimeFormatter format (for example, HH:mm:ss for a two-digit hour in 24-hour format, followed by a two-digit minute, followed by a two-digit second, all separated by ‘:’ characters, as in 18:04:15).
Timestamp Format	Timestamp Format			Specifies the format to use when reading/writing Timestamp fields. If not specified, Timestamp fields will be assumed to be number of milliseconds since epoch (Midnight, Jan 1, 1970 GMT). If specified, the value must match the Java java.time.format.DateTimeFormatter format (for example, MM/dd/yyyy HH:mm:ss for a two-digit month, followed by a two-digit day, followed by a four-digit year, all separated by ‘/’ characters; and then followed by a two-digit hour in 24-hour format, followed by a two-digit minute, followed by a two-digit second, all separated by ‘:’ characters, as in 01/01/2017 18:04:15).
Trim Fields *	Trim Fields	true	true false	Whether or not white space should be removed from the beginning and end of fields
Value Separator *	Value Separator	,		The character that is used to separate values/fields in a CSV Record. If the property has been specified via Expression Language but the expression gets evaluated to an invalid Value Separator at runtime, then it will be skipped and the default Value Separator will be used.
CSV Writer *	csv-writer	commons-csv	Apache Commons CSV FastCSV	Specifies which writer implementation to use to write CSV records. NOTE: Different writers may support different subsets of functionality and may also exhibit different levels of performance.
