KinoSearch::Index::BacUseruContributed PKinoSearch::Index::BackgroundMerger(3)NAMEKinoSearch::Index::BackgroundMerger - Consolidate index segments in the
background.
SYNOPSIS
my $bg_merger = KinoSearch::Index::BackgroundMerger->new(
index => '/path/to/index',
);
$bg_merger->commit;
DESCRIPTION
Adding documents to an index is usually fast, but every once in a while
the index must be compacted and an update takes substantially longer to
complete. See KinoSearch::Docs::Cookbook::FastUpdates for how to use
this class to control worst-case index update performance.
As with Indexer, see KinoSearch::Docs::FileLocking if your index is on
a shared volume.
CONSTRUCTORS
new( [labeled params] )
my $bg_merger = KinoSearch::Index::BackgroundMerger->new(
index => '/path/to/index', # required
manager => $manager # default: created internally
);
Open a new BackgroundMerger.
· index - Either a string filepath or a Folder.
· manager - An IndexManager. If not supplied, an IndexManager with a
10-second write lock timeout will be created.
METHODScommit()
Commit any changes made to the index. Until this is called, none of
the changes made during an indexing session are permanent.
Calls prepare_commit() implicitly if it has not already been called.
prepare_commit()
Perform the expensive setup for commit() in advance, so that commit()
completes quickly.
Towards the end of prepare_commit(), the BackgroundMerger attempts to
re-acquire the write lock, which is then held until commit() finishes
and releases it.
optimize()
Optimize the index for search-time performance. This may take a while,
as it can involve rewriting large amounts of data.
INHERITANCEKinoSearch::Index::BackgroundMerger isa KinoSearch::Object::Obj.
