Matt Burgess commented on NIFI-6496:
------------------------------------
Can we resolve this as superseded by NIFI-11466 ? ModifyCompression can change
the compression using buffered input/output streams without spilling the
contents to disk in the meantime.
> Add compression support to record reader processor
> --------------------------------------------------

> Key: NIFI-6496
> URL: https://issues.apache.org/jira/browse/NIFI-6496
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Reporter: Malthe Borch
> Priority: Minor
> Labels: easyfix, usability
>
> Text-based record formats such as CSV, JSON and XML compress well and will
> often be transmitted in a compressed format. If compression support is added
> to the relevant processors, users will not need to explicitly unpack files
> before processing (which may not be feasible or practical due to space
> requirements).
> There are at least two ways of implementing this, using either a generic
> approach where a {{CompressedRecordReaderFactory}} is the basis for a new
> controller service that wraps the underlying record reader controller service
> (e.g. {{CSVReader}}); or adding the functionality at the relevant record
> reader implementations.
> The latter option may provide a better UX because no additional
> {{ControllerService}} has to be configured.
