Notable changes to createrepo_c

Review the most notable changes to createrepo_c between RHEL 9 and RHEL 10.

Default createrepo_c compression changed from gzip to Zstandard
The createrepo_c command compresses non-database metadata with the Zstandard (zstd) compression algorithm instead of gzip. Note that the database metadata still defaults to the bzip2 format. You can override the compression format by using the --general-compress-type option.
SQLite databases are not generated by default

To save disk space, the createrepo_c command no longer creates SQLite databases next to XML files. You can explicitly create the databases by using the --database option.

Note
Support for creating the SQLite databases with the createrepo --databases command is deprecated and will be removed in future RHEL major versions.
