Class BulkProcessor

java.lang.Object

org.elasticsearch.action.bulk.BulkProcessor

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

public class BulkProcessor
extends java.lang.Object
implements java.io.Closeable

A bulk processor is a thread safe bulk processing class, allowing to easily set when to "flush" a new bulk request (either based on number of actions, based on the size, or time), and to easily control the number of concurrent bulk requests allowed to be executed in parallel.

In order to create a new bulk processor, use the BulkProcessor.Builder.

Method Detail

builder

public static BulkProcessor.Builder builder(Client client,
                                            BulkProcessor.Listener listener)

close

public void close()

Closes the processor. If flushing by time is enabled, then it's shutdown. Any remaining bulk actions are flushed.

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface java.lang.AutoCloseable

awaitClose

public boolean awaitClose(long timeout,
                          java.util.concurrent.TimeUnit unit)
                   throws java.lang.InterruptedException

Closes the processor. If flushing by time is enabled, then it's shutdown. Any remaining bulk actions are flushed.

If concurrent requests are not enabled, returns true immediately. If concurrent requests are enabled, waits for up to the specified timeout for all bulk requests to complete then returns true, If the specified waiting time elapses before all bulk requests complete, false is returned.

Parameters:

timeout - The maximum time to wait for the bulk requests to complete

unit - The time unit of the timeout argument

Returns:

true if all bulk requests completed and false if the waiting time elapsed before all the bulk requests completed

Throws:

java.lang.InterruptedException - If the current thread is interrupted

add

public BulkProcessor add(IndexRequest request)

Adds an IndexRequest to the list of actions to execute. Follows the same behavior of IndexRequest (for example, if no id is provided, one will be generated, or usage of the create flag).

add

public BulkProcessor add(DeleteRequest request)

Adds an DeleteRequest to the list of actions to execute.

add

public BulkProcessor add(DocWriteRequest request)

Adds either a delete or an index request.

add

public BulkProcessor add(DocWriteRequest request,
                         @Nullable
                         java.lang.Object payload)

ensureOpen
