NAME

KinoSearch::Architecture - Configure major components of an index.

SYNOPSIS

    package MyArchitecture;
    use base qw( KinoSearch::Architecture );

    use KSx::Index::ZlibDocWriter;
    use KSx::Index::ZlibDocReader;

    sub register_doc_writer {
        my ( $self, $seg_writer ) = @_; 
        my $doc_writer = KSx::Index::ZlibDocWriter->new(
            snapshot   => $seg_writer->get_snapshot,
            segment    => $seg_writer->get_segment,
            polyreader => $seg_writer->get_polyreader,
        );  
        $seg_writer->register(
            api       => "KinoSearch::Index::DocReader",
            component => $doc_writer,
        );  
        $seg_writer->add_writer($doc_writer);
    }

    sub register_doc_reader {
        my ( $self, $seg_reader ) = @_; 
        my $doc_reader = KSx::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       => 'KinoSearch::Index::DocReader',
            component => $doc_reader,
        );  
    }
 
    package MySchema;

    }

DESCRIPTION

By default, a KinoSearch 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.

METHODS

register_doc_writer(writer)

Spawn a DataWriter and register() it with the supplied SegWriter, adding it to the SegWriter's writer stack.

  • writer - A SegWriter.

register_doc_reader(reader)

Spawn a DocReader and register() it with the supplied SegReader.

  • reader - A SegReader.

INHERITANCE

KinoSearch::Architecture isa KinoSearch::Obj.
