Package org.nuxeo.elasticsearch.bulk

Class BulkIndexComputation

java.lang.Object

org.nuxeo.lib.stream.computation.AbstractComputation

org.nuxeo.elasticsearch.bulk.BulkIndexComputation

All Implemented Interfaces:

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

public class BulkIndexComputation
extends AbstractComputation
implements org.opensearch.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.

Method Details

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.opensearch.action.bulk.BulkRequest decodeRequest(DataBucket bucket)

beforeBulk

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

Specified by:

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

afterBulk

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

Specified by:

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

afterBulk

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

Specified by:

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