> 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.
