Hibernate Search 3.3.0 Final：Massindexer 需要很长时间才能建立索引

Question

嗨，我有以下课程。用户视图是oracle中的物化视图。

  public class UserView {
        @DocumentId
        private Integer           id;

        @Fields({ @Field(index = Index.TOKENIZED, store = Store.YES),
                @Field(name = "username_sort", index = Index.UN_TOKENIZED, store = Store.NO) })
        @Boost(value = 2.5f)
        private String            username;

        @Fields({ @Field(index = Index.TOKENIZED, store = Store.YES),
                @Field(name = "email_sort", index = Index.UN_TOKENIZED, store = Store.NO) })
        @Boost(value = 2)
        private String            email;

        @Fields({ @Field(index = Index.TOKENIZED, store = Store.YES),
                @Field(name = "firstname_sort", index = Index.UN_TOKENIZED, store = Store.NO)    })
        @Boost(value = 1.5f)
        private String            firstname;

        @Fields({ @Field(index = Index.TOKENIZED, store = Store.YES),
                @Field(name = "lastname_sort", index = Index.UN_TOKENIZED, store = Store.NO) })
        @Boost(value = 1.5f)
        private String            lastname;

        @Field(index = Index.NO_NORMS)
        @DateBridge(resolution = Resolution.MILLISECOND)
        private Timestamp         createDate;

        @IndexedEmbedded(depth = 1, prefix = "createBy_")
        private UserView          createdBy;

        @Field(index = Index.TOKENIZED)
        @DateBridge(resolution = Resolution.MILLISECOND)
        private Timestamp         modifyDate;

        @IndexedEmbedded(depth = 1, prefix = "modifyBy_")
        private UserView          modifiedBy;
    }

我有用于批量索引的数据访问对象，如下所示。

private static class BatchProcessUserReindex implements HibernateCallback<Future<?>> {
        private final Logger LOG = LoggerFactory.getLogger(this.getClass());

        private final int    batchSize;
        private final int    fetchSize;

        public BatchProcessUserReindex(final int batchSize, final int fetchSize) {
            super();
            this.batchSize = batchSize;
            this.fetchSize = fetchSize;
        }

        @Override
        public Future<?> doInHibernate(final Session session) {
            final Integer threadsToLoadObject = (this.fetchSize / this.batchSize);
            final Integer threadsForFetch = (this.batchSize/threadsToLoadObject) * threadsToLoadObject;
            final FullTextSession fullTextSession = Search.getFullTextSession(session);
            final Future<?> batchProcesses = fullTextSession.createIndexer(UserView.class)
                    .batchSizeToLoadObjects(this.batchSize)
                    .threadsForSubsequentFetching(threadsForFetch)
                    .threadsToLoadObjects(threadsToLoadObject)
                    .start();
            batchProcesses.get(); // block all incoming request. 
            if (this.LOG.isDebugEnabled()) {
                final Statistics stat = fullTextSession.getSearchFactory().getStatistics();
                this.LOG.debug("batch size {}", this.batchSize);
                this.LOG.debug("threads for fetch {}", threadsForFetch);
                this.LOG.debug("threads to load object {}", threadsToLoadObject);
                this.LOG.debug("average loading execution time: {}", stat.getObjectLoadingExecutionAvgTime());
                this.LOG.debug("maximum loading time: {}", stat.getObjectLoadingExecutionMaxTime());
                this.LOG.debug("total time to load object: {}", stat.getObjectLoadingTotalTime());
                this.LOG.debug("total object loaded: {}", stat.getObjectsLoadedCount());
                this.LOG.debug("average search time: {}", stat.getSearchQueryExecutionAvgTime());
                this.LOG.debug("maximum search time: {}", stat.getSearchQueryExecutionMaxTime());
                this.LOG.debug("total time to search object: {}", stat.getSearchQueryTotalTime());
                this.LOG.debug("total object search: {}", stat.getSearchQueryExecutionCount());
                this.LOG.debug("query with slowest search: {}", stat.getSearchQueryExecutionMaxTimeQueryString());
            }
            return batchProcesses;
        }
    }

我的批量大小为 25，获取大小为 200。 所以我的批量交易设置。

@Transactional(propagation = Propagation.REQUIRES_NEW,
            isolation = Isolation.READ_COMMITTED)

这是我的属性设置。

hibernate.search.User.directory_provider=filesystem-master
hibernate.search.User.optimizer.operation_limit.max=500
hibernate.search.User.optimizer.transaction_limit.max=50
hibernate.search.User.locking_strategy=native
hibernate.search.User.indexwriter.batch.merge_factor=32
hibernate.search.User.indexwriter.batch.ram_buffer_size=64
hibernate.search.User.indexwriter.batch.max_merge_docs=2147483647
hibernate.search.User.indexwriter.batch.max_buffered_docs=64
hibernate.search.User.exclusive_index_use=true
hibernate.search.User.refresh=7200
hibernate.search.User.buffer_size_on_copy=64
hibernate.search.generate_statistics=true

所以我开始索引，结果花了 7 分钟多，没有结果（而且我系统中只有 20 个用户）？？？

怎么了？为什么需要这么长时间。

这是跟踪日志文件。
