Package org.nuxeo.elasticsearch.bulk

Class BulkIndexComputation

java.lang.Object

org.nuxeo.lib.stream.computation.AbstractComputation

org.nuxeo.elasticsearch.bulk.BulkIndexComputation

All Implemented Interfaces:

org.elasticsearch.action.bulk.BulkProcessor.Listener, Computation

public class BulkIndexComputation
extends AbstractComputation
implements org.elasticsearch.action.bulk.BulkProcessor.Listener

A computation that submits elasticsearch requests using the bulk API.

Note that the retry policy is handled by the elasticsearch bulk processor.

Since:

10.3

Constructor Detail

BulkIndexComputation

public BulkIndexComputation(int esBulkSize,
                            int esBulkActions,
                            int flushInterval)

Method Detail

init

public void init(ComputationContext context)

Description copied from interface: Computation

Called when the framework has registered the computation successfully. Gives users a first opportunity to schedule timer callbacks and produce records. This method can be called multiple times.

Specified by:

init in interface Computation

Overrides:

init in class AbstractComputation

Parameters:

context - The computation context object provided by the system.

processTimer

public void processTimer(ComputationContext context,
                         String key,
                         long timestamp)

Description copied from interface: Computation

Process a timer callback previously set via ComputationContext.setTimer(String, long).

Specified by:

processTimer in interface Computation

Overrides:

processTimer in class AbstractComputation

Parameters:

context - The computation context object provided by the system.

key - The name of the timer.

timestamp - The timestamp (in ms) for which the callback was scheduled.

processRecord

public void processRecord(ComputationContext context,
                          String inputStream,
                          Record record)

Description copied from interface: Computation

Process an incoming record on one of the computation's input streams.

Specified by:

processRecord in interface Computation

Parameters:

context - The computation context object provided by the system.

inputStream - Name of the input stream that provides the record.

record - The record.

destroy

public void destroy()

Description copied from interface: Computation

Called when the framework is ready to shutdown the computation. Gives users a chance to perform some cleanup before the process is killed.

Specified by:

destroy in interface Computation

getESClient

protected ESClient getESClient()

decodeRequest

protected org.elasticsearch.action.bulk.BulkRequest decodeRequest(DataBucket bucket)

beforeBulk

public void beforeBulk(long executionId,
                       org.elasticsearch.action.bulk.BulkRequest request)

Specified by:

beforeBulk in interface org.elasticsearch.action.bulk.BulkProcessor.Listener

afterBulk

public void afterBulk(long executionId,
                      org.elasticsearch.action.bulk.BulkRequest request,
                      org.elasticsearch.action.bulk.BulkResponse response)

Specified by:

afterBulk in interface org.elasticsearch.action.bulk.BulkProcessor.Listener

afterBulk

public void afterBulk(long executionId,
                      org.elasticsearch.action.bulk.BulkRequest request,
                      Throwable failure)

Specified by:

afterBulk in interface org.elasticsearch.action.bulk.BulkProcessor.Listener
