Interface MassIndexer

@Deprecated public interface MassIndexer
Deprecated.
Instead of using Hibernate Search 5 APIs, get a SearchSession using Search.session(Session), then create a mass indexer with SearchSession.massIndexer(Class[]). Refer to the migration guide for more information.
A MassIndexer is useful to rebuild the indexes from the data contained in the database. This process is expensive: all indexed entities and their indexedEmbedded properties are scrolled from database.

      @Deprecated MassIndexer threadsForSubsequentFetching(int numberOfThreads)
      Deprecated.
      Being ignored: this method will be removed.
      Deprecated: value is ignored.
      Parameters:
      numberOfThreads - the number of threads
      Returns:
      this for method chaining

    • progressMonitor

      MassIndexer progressMonitor(MassIndexerProgressMonitor monitor)
      Deprecated.
      Override the default MassIndexerProgressMonitor.
      Parameters:
      monitor - this instance will receive updates about the massindexing progress.
      Returns:
      this for method chaining

    • cacheMode

      MassIndexer cacheMode(org.hibernate.CacheMode cacheMode)
      Deprecated.
      Sets the cache interaction mode for the data loading tasks. Defaults to CacheMode.IGNORE.
      Parameters:
      cacheMode - the cache interaction mode
      Returns:
      this for method chaining

    • optimizeOnFinish

      MassIndexer optimizeOnFinish(boolean optimize)
      Deprecated.
      If index optimization has to be started at the end of the indexing process. Defaults to true.
      Parameters:
      optimize - true to enable the index optimization at the end of the indexing process
      Returns:
      this for method chaining

    • optimizeAfterPurge

      MassIndexer optimizeAfterPurge(boolean optimize)
      Deprecated.
      If index optimization should be run before starting, after the purgeAll. Has no effect if purgeAll is set to false. Defaults to true.
      Parameters:
      optimize - true to enable the index optimization after purge
      Returns:
      this for method chaining

    • purgeAllOnStart

      MassIndexer purgeAllOnStart(boolean purgeAll)
      Deprecated.
      If all entities should be removed from the index before starting using purgeAll. Set it to false only if you know there are no entities in the index: otherwise search results may be duplicated. Defaults to true.
      Parameters:
      purgeAll - if true all entities will be removed from the index before starting the indexing
      Returns:
      this for method chaining

    • limitIndexedObjectsTo

      MassIndexer limitIndexedObjectsTo(long maximum)
      Deprecated.
      EXPERIMENTAL method: will probably change Will stop indexing after having indexed a set amount of objects. As a results the index will not be consistent with the database: use only for testing on an (undefined) subset of database data.
      Parameters:
      maximum - the maximum number of objects to index
      Returns:
      this for method chaining

    • start

      Future<?> start()
      Deprecated.
      Starts the indexing process in background (asynchronous). Can be called only once.
      Returns:
      a Future to control the indexing task.

    • startAndWait

      void startAndWait() throws InterruptedException
      Deprecated.
      Starts the indexing process, and then block until it's finished. Can be called only once.
      Throws:
      InterruptedException - if the current thread is interrupted while waiting.

    • idFetchSize

      MassIndexer idFetchSize(int idFetchSize)
      Deprecated.
      Specifies the fetch size to be used when loading primary keys if objects to be indexed. Some databases accept special values, for example MySQL might benefit from using Integer.MIN_VALUE otherwise it will attempt to preload everything in memory.
      Parameters:
      idFetchSize - the fetch size to be used when loading primary keys
      Returns:
      this for method chaining

    • transactionTimeout

      MassIndexer transactionTimeout(int timeoutInSeconds)
      Deprecated.
      Timeout of transactions for loading ids and entities to be re-indexed. Specify a timeout which is long enough to load and index all entities of the type with the most instances, taking into account the configured batch size and number of threads to load objects.

      Only supported in JTA-compatible environments.

      Parameters:
      timeoutInSeconds - the transaction timeout in seconds; If no value is given, the global default timeout of the JTA environment applies.
      Returns:
      this for method chaining
