[pcp:master] New Comment on Issue #188 compressed archive volumes hobble pmwebd graphite webapi (Bugzilla #1099) ( https://github.com/performancecopilot/pcp/issues/188 )
By goodwinos ( https://github.com/goodwinos ) :

I will open a RH BZ for Red Hat support case 01745906. Apparently the xz compressed format already being used for PCP archive compression has an API called liblzma that supports block-level random access to xz files. Not sure what block sizes are supported, but this should in principle provide what's needed for libpcp to read compressed archives insitu, without having to decompress them to temp space. See below /usr/src/debug/xz-5.2.2/src/liblzma/api in the xz-debuginfo package (or look in the xz source itself).
