https://perconadev.atlassian.net/browse/PS-10243 Changed the definition of the 'util::bounded_string_storage' - instead of being 'std::array<std::byte, N>', it is now 'boost::container::static_vector<std::byte, N>' which is more appropriate because it holds real size in one of its members eliminating the necessity to do 'strlen()' every time we want to use this data as a string. This affected 'server_version' member in the FORMAT_DESCRIPTION event post header and 'tag' in the the GTID_TAGGED_LOG event body. In addition, changed the underlying container for storing 'binlog' member (file name) in the ROTATE event body: instead of 'std::string', we now use 'boost::container::small_vector<std::byte, 64> which will let us avoid dynamic allocations for file names up to 64 bytes.
