Bug ID: 30378
Summary: need better compression of the _files table
Product: elfutils
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: debuginfod
Assignee: unassigned at sourceware dot org
Reporter: fche at redhat dot com
CC: elfutils-devel at sourceware dot org
Target Milestone: ---
Enumerating each file name (whether an archive name or a file within an archive
or a source file name referenced from a dwarf file) inside the _files table
means storing many near-duplicate strings in that table. Considering splitting
it up into basename / dirname subtables, with _files containing their id-pair
only rather than a potentially long string. Expecting drastic reduction in
sqlite data size.
