NAME

TM::ResourceAble::MemCached - Topic Maps, Memcached server backend

SYNOPSIS

    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 ],
             );

DESCRIPTION

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.

INTERFACE

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).
