> It would be nice to be able to specify exactly which records or ranges of records are sampled from a FlowFile. For example if the first 5 lines of a comma-delimited file are free-text (meaning it's not technically a CSV file from NiFi's perspective as the first 5 lines do not constitute a header in this example), it would be handy to be able to exclude them by specifying a range filter of "6-" to say the 6th and every following record should be output.
> In that vein SampleRecord could have a "range sampling" strategy where the user could specify something like "2, 5-7, 25-" where the second, fifth, sixth, seventh, and every record from the twenty-fifth record on would be included in the outgoing flow file.
