Entertaining Pixie

A lightening talk by Steve Purkis

What is Pixie?

• An object persistency engine

• Very basic idea– Store objects in a data source

• Very simple api…

Synopsisuse Pixie;

my $pixie = Pixie->new->connect( 'memory' );my $obj = SomeObject->new;

# Store an objectmy $cookie = $pixie->insert( $obj );

undef( $obj );

# Fetch it backmy $obj = $pixie->get( $cookie );

# Give it a name$pixie->bind_name( "Some Name" => $obj );my $obj2 = $pixie->get_object_named( "Some Name" );

# Delete it$pixie->delete( $cookie ) || warn "eek!";

What is Pixie?

• No db schemas. No complex queries.• You can focus on the code.• Supports various data sources:

– MySQL– Postgresql– SQLite– BerkeleyDB– Memory (for testing)

As usual…

• It’s on CPAN• It’s been tested• If you’ve any problems let us know

(see http://pixie-perl.sourceforge.net/ )

So what’s the deal?

• It’s been tested

• It’s on CPAN

• It works

So what’s the deal?

• It can be a pain to use

• It’s slow

• It’s not that scaleable(you were right, Arthur)

• The guts need cleaning up

• It could be more extensible
