I've got it, we want to use:
http://httpd.apache.org/docs/trunk/rewrite/rewritemap.html#dbm

which allows using a map file with additional index. There's svn-to-git.txt file:
https://drive.google.com/file/d/1xZ7TwvqcV6zErup920OLhb09tePgSJHQ/view?usp=sharing

that should be transformed by:
$ httxt2dbm -i svn-to-git.txt -o svn-to-git.map
