now, when compress is passed as True, it will use zip instead.
Thus, there's almost no possibility to use lz4 case.
However, LZ4 has a better CPU performance comparing to zip, thus let's keep this issue open and in future allow user to select which compression type to use.

zip is enough. don't need it in real case. won't fix.
