TM::ResourceAble::MemCached - Topic Maps, Memcached server backend
use TM::ResourceAble::MemCached; use Fcntl; # create/reset new map my $tm = new TM::ResourceAble::MemCached ( baseuri => 'http://whereever/', servers => [ localhost:11211 ], mode => O_TRUNC | O_CREAT, ); # use TM interface # open existing map my $tm = new TM::ResourceAble::MemCached ( baseuri => 'http://whereever/', servers => [ localhost:11211 ], );
This package implements TM using a memcached server farm as backend. You should be able (without much testing, mind you, so it is EXPERIMENTAL) to perform all operations according to the TM interface. NOTE: The implementation is using the TIE technique (perltie via Tie::StdHash), so maybe there are problems lurking. Of course, a set of memcacheds can store any number of maps. To keep them separate, the baseuri is used, so make sure every map gets its own baseuri.
Constructor The constructor expects a hash with the following keys: servers (default: none) The value must be a reference to an array of strings, each of the form host:port. If there is no such list, then the constructor will fail. mode (default: O_CREAT) The value must be a value from Fcntl to control · whether the map should be created ("O_CREAT") when it does not exist, and/or · whether the map should be cleared ("O_TRUNC") when it existed before. All other options are passed to the constructor chain of traits (TM::ResourceAble) and superclasses (TM).
