Hi I have the following class. User view is materialized view in oracle.
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;
}
Than I have the Data access object for mass indexing as follow.
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;
}
}
I have batch size as 25 and fetch size as 200.
So my transaction setting for batching.
@Transactional(propagation = Propagation.REQUIRES_NEW,
isolation = Isolation.READ_COMMITTED)
Here are my properties setting.
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
So I start indexing and it ends up taking more than 7 minutes and no result (and I only have 20 user in the system)?????
What is wrong? Why does it take so long.
Here is the trace log file.
