Dirk Rudolph updated JCRVLT-259:
--------------------------------
Description:
The new feature to suppress compression for already compressed binaries
introduced in JCRVLT-163, has been implemented with Apache Sling Content
Distribution in mind to get best performance while still keep bytes on the wire
as small as affordable [0].
Wouldn't it make sense for such cases to support different formats as well,
especially thinking about snappy or lz4?
Currently there is a pair for compressing and decompressing implementations,
JarExporter and ZipArchive/ZipStreamArchive. Those are used by the
PackageManagerImpl for example to open or assemble a new package. Adding
support for further compression formats could be done for example by
implementing a registry holding the constructors for compression and
decompression implementations, where the one of choice could be requested by
the ExportOptions (defaulting to jar/zip as it is now).
