NAME

KinoSearch::Index::IndexManager - Policies governing index updating, locking, and file deletion.

DEPRECATED

The KinoSearch code base has been assimilated by the Apache Lucy project. The "KinoSearch" namespace has been deprecated, but development continues under our new name at our new home: http://lucy.apache.org/

SYNOPSIS

    use Sys::Hostname qw( hostname );
    my $hostname = hostname() or die "Can't get unique hostname";
    my $manager = KinoSearch::Index::IndexManager->new( 
        host => $hostname,
    );

    # Index time:
    my $indexer = KinoSearch::Index::Indexer->new(
        index => '/path/to/index',
        manager => $manager,
    );

    # Search time:
    my $reader = KinoSearch::Index::IndexReader->open(
        index   => '/path/to/index',
        manager => $manager,
    );
    my $searcher = KinoSearch::Search::IndexSearcher->new( index => $reader );

DESCRIPTION

IndexManager is an advanced-use class for controlling index locking, updating, merging, and deletion behaviors.

IndexManager and Architecture are complementary classes: Architecture is used to define traits and behaviors which cannot change for the life of an index; IndexManager is used for defining rules which may change from process to process.

CONSTRUCTORS

new( [labeled params] )

    my $manager = KinoSearch::Index::IndexManager->new(
        host => $hostname,    # default: ""
    );
  • host - An identifier which should be unique per-machine.

  • lock_factory - A LockFactory.

METHODS

make_write_lock()

Create the Lock which controls access to modifying the logical content of the index.

recycle( [labeled params] )

Return an array of SegReaders representing segments that should be consolidated. Implementations must balance index-time churn against search-time degradation due to segment proliferation. The default implementation prefers small segments or segments with a high proportion of deletions.

  • reader - A PolyReader.

  • del_writer - A DeletionsWriter.

  • cutoff - A segment number which all returned SegReaders must exceed.

  • optimize - A boolean indicating whether to spend extra time optimizing the index for search-time performance.

set_folder(folder)

Setter for folder member. Typical clients (Indexer, IndexReader) will use this method to install their own Folder instance.

get_folder()

Getter for folder member.

get_host()

Getter for host member.

set_write_lock_timeout(timeout)

Setter for write lock timeout. Default: 1000 milliseconds.

get_write_lock_timeout()

Getter for write lock timeout.

set_write_lock_interval(timeout)

Setter for write lock retry interval. Default: 100 milliseconds.

get_write_lock_interval()

Getter for write lock retry interval.

INHERITANCE

KinoSearch::Index::IndexManager isa KinoSearch::Object::Obj.
