ReaderLookup

Description:

Provides a RecordReaderFactory that can be used to dynamically select another RecordReaderFactory. This service requires an variable named 'recordreader.name' to be passed in when asking for a record record, and will throw an exception if the variable is missing. The value of 'recordreader.name' will be used to select the RecordReaderFactory that has been registered with that name. This will allow multiple RecordReaderFactory's to be defined and registered, and then selected dynamically at runtime by tagging flow files with the appropriate 'recordreader.name' variable.
