Class BulkProcessor

java.lang.Object

lumis.portal.bigdata.elasticsearch.BulkProcessor

All Implemented Interfaces:

Closeable, AutoCloseable

public class BulkProcessor
extends Object
implements 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 Builder.

Method Detail

builder

public static lumis.portal.bigdata.elasticsearch.BulkProcessor.Builder builder(org.elasticsearch.client.Client client,
                                                                               lumis.portal.bigdata.elasticsearch.BulkProcessor.Listener listener)

builder

public static lumis.portal.bigdata.elasticsearch.BulkProcessor.Builder builder(java.util.function.BiConsumer<org.elasticsearch.action.bulk.BulkRequest,org.elasticsearch.action.ActionListener<org.elasticsearch.action.bulk.BulkResponse>> consumer,
                                                                               lumis.portal.bigdata.elasticsearch.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 Closeable

Specified by:

close in interface AutoCloseable

awaitClose

public boolean awaitClose(long timeout,
                          TimeUnit unit)
                   throws 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:

InterruptedException - If the current thread is interrupted

add

public BulkProcessor add(org.elasticsearch.action.index.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(org.elasticsearch.action.delete.DeleteRequest request)

Adds an DeleteRequest to the list of actions to execute.

add

public BulkProcessor add(org.elasticsearch.action.DocWriteRequest<?> request)

Adds either a delete or an index request.

ensureOpen

protected void ensureOpen()

add

public BulkProcessor add(org.elasticsearch.common.bytes.BytesReference data,
                         @Nullable
                         String defaultIndex,
                         @Nullable
                         String defaultType,
                         org.elasticsearch.common.xcontent.XContentType xContentType)
                  throws Exception

Adds the data from the bytes to be processed by the bulk processor

Throws:

Exception

add

                         @Nullable
                         String defaultIndex,
                         @Nullable
                         String defaultType,
                         @Nullable
                         String defaultPipeline,
                         org.elasticsearch.common.xcontent.XContentType xContentType)
                  throws Exception

Adds the data from the bytes to be processed by the bulk processor

Throws:

Exception

flush

public void flush()

Flush pending delete or index requests.
