Puts record field data into Redis using a specified hash value, which is determined by a RecordPath to a field in each record containing the hash value. The record fields and values are stored as key/value pairs associated by the hash value. NOTE: Neither the evaluated hash value nor any of the field values can be null. If the hash value is null, the FlowFile will be routed to failure. For each of the field values, if the value is null that field will be not set in Redis.

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, and whether a property supports the NiFi Expression Language.
| Display Name | API Name | Default Value | Allowable Values | Description |
|---|---|---|---|---|
| Record Reader | record-reader | Controller Service API: RecordReaderFactory Implementations: CSVReader JsonPathReader AvroReader CEFReader Syslog5424Reader JsonTreeReader WindowsEventLogReader XMLReader SyslogReader JASN1Reader ReaderLookup ParquetReader GrokReader ScriptedReader YamlTreeReader ExcelReader | Specifies the Controller Service to use for parsing incoming data and determining the data's schema | |
| Redis Connection Pool | redis-connection-pool | Controller Service API: RedisConnectionPool Implementation: RedisConnectionPoolService | No Description Provided. | |
| Hash Value Record Path | hash-value-record-path | Specifies a RecordPath to evaluate against each Record in order to determine the hash value associated with all the record fields/values (see 'hset' in Redis documentation for more details). The RecordPath must point at exactly one field or an error will occur. | ||
| Data Record Path | data-record-path | / | This property denotes a RecordPath that will be evaluated against each incoming Record and the Record that results from evaluating the RecordPath will be sent to Redis instead of sending the entire incoming Record. The property defaults to the root '/' which corresponds to a 'flat' record (all fields/values at the top level of the Record. | |
| Character Set | charset | UTF-8 | Specifies the character set to use when storing record field values as strings. All fields will be converted to strings using this character set before being stored in Redis. Supports Expression Language: true (will be evaluated using flow file attributes and Environment variables) |
| Name | Description |
|---|---|
| success | FlowFiles having all Records stored in Redis will be routed to this relationship |
| failure | FlowFiles containing Records with processing errors will be routed to this relationship |
| Name | Description |
|---|---|
| redis.success.record.count | Number of records written to Redis |
