Class ElasticsearchWorkProcessor

java.lang.Object

org.hibernate.search.elasticsearch.processor.impl.ElasticsearchWorkProcessor

All Implemented Interfaces:

AutoCloseable

public class ElasticsearchWorkProcessor
extends Object
implements AutoCloseable

Executes single or multiple ElasticsearchWorks against the Elasticsearch server.

When processing multiple requests, bulk requests will be formed and executed as far as possible.

Requests can be processed synchronously or asynchronously. In the latter case, incoming requests are added to a queue via AsyncBackendRequestProcessor from where a worker runnable will process them in bulks.

Method Detail

close

public void close()

Specified by:

close in interface AutoCloseable

executeSyncUnsafe

public <T> T executeSyncUnsafe(ElasticsearchWork<T> work)

Executes a work synchronously, potentially throwing exceptions (the error handler isn't used).

executeSyncSafe

public void executeSyncSafe(Iterable<ElasticsearchWork<?>> requests)

Executes works synchronously, passing any thrown exception to the error handler.

executeAsync

public void executeAsync(ElasticsearchWork<?> request)

Executes a work asynchronously, passing any exception to the error handler.

awaitAsyncProcessingCompletion

public void awaitAsyncProcessingCompletion()

Blocks until the queue of requests scheduled for asynchronous processing has been fully processed. N.B. if more work is added to the queue in the meantime, this might delay the wait.
