NAME
Lucy::Plan::Architecture - Configure major components of an index.
SYNOPSIS
package MyArchitecture;
use base qw( Lucy::Plan::Architecture );
use LucyX::Index::ZlibDocWriter;
use LucyX::Index::ZlibDocReader;
sub register_doc_writer {
my ( $self, $seg_writer ) = @_;
my $doc_writer = LucyX::Index::ZlibDocWriter->new(
snapshot => $seg_writer->get_snapshot,
segment => $seg_writer->get_segment,
polyreader => $seg_writer->get_polyreader,
);
$seg_writer->register(
api => "Lucy::Index::DocReader",
component => $doc_writer,
);
$seg_writer->add_writer($doc_writer);
}
sub register_doc_reader {
my ( $self, $seg_reader ) = @_;
my $doc_reader = LucyX::Index::ZlibDocReader->new(
schema => $seg_reader->get_schema,
folder => $seg_reader->get_folder,
segments => $seg_reader->get_segments,
seg_tick => $seg_reader->get_seg_tick,
snapshot => $seg_reader->get_snapshot,
);
$seg_reader->register(
api => 'Lucy::Index::DocReader',
component => $doc_reader,

package MySchema;
use base qw( Lucy::Plan::Schema );
sub architecture {
shift;
return MyArchitecture->new(@_);
}
DESCRIPTION
By default, a Lucy index consists of several main parts: lexicon, postings, stored
documents, deletions, and highlight data. The readers and writers for that data are
spawned by Architecture. Each component operates at the segment level; Architecture's
factory methods are used to build up SegWriter and SegReader.
