Problem description
Insert data in Elasticsearch.
Important parameters:
throughput = 50 records/s
bulk concurrent requests = 2
bulk max actions = 10
bulk max size = 90 (never triggers insertions)
BulkIngester
bulkIngester = BulkIngester.of(b -> b
.client(client)
.maxOperations(bulkMaxActions)
.maxConcurrentRequests(bulkConcurrentRequests)
.maxSize(bulkMaxSize * 1024L * 1024)
.listener(esBulkListener));BulkListener
public class EsBulkListener implements BulkListener<byte[]> {
private static final Logger LOG = LogManager.getLogger(EsBulkListener.class);
private AckCounter ackCounter;
private boolean acknowledgeRecords;
public EsBulkListener(boolean acknowledgeRecords) {
this.ackCounter = new AckCounter();
this.acknowledgeRecords = acknowledgeRecords;
}
@Override
public void beforeBulk(long executionId, BulkRequest request, List<byte[]> contexts) {
//LOG.info("BulkIngester Execution (" + executionId + ") - About to execute new bulk insert composed of " + request.operations().size() + " actions");
}
@Override
public void afterBulk(long executionId, BulkRequest request, List<byte[]> contexts, BulkResponse response) {
if (response.errors()) {
LOG.error("BulkIngester Bulk Response has failures: " + response.errors());
if (acknowledgeRecords) {
response.items().forEach(i -> {
if (i.error() != null) {
ackCounter.updateFailure(1L);
} else {
ackCounter.updateSuccess(1L);
}
});
}
} else {
//LOG.info("BulkIngester Execution (" + executionId + ") - Bulk insert composed of " + request.operations().size() +" actions, took " + response.took() + " ms");
if (acknowledgeRecords) {
ackCounter.updateSuccess(request.operations().size());
}
}
}
@Override
public void afterBulk(long executionId, BulkRequest request, List<byte[]> contexts, Throwable failure) {
LOG.error("BulkIngester (" + executionId + ") - Execution of bulk request failed: " + failure.getMessage());
if (acknowledgeRecords) {
ackCounter.updateFailure(request.operations().size());
}
}
AckCounter getAckCounter() {
return ackCounter;
}
}Insertion:
public void send(Object record) {
Map<String, Object> esValues = (Map<String, Object>)record;
String docId = (String) esValues.remove(DOC_ID);
bulkIngester.add(op -> op
.index(ind -> ind
.id(docId)
.index(indexName)
.document(esValues)));
}Set Elasticsearch master down to fail insertions in Elasticsearch.
You have errors: bulk request failed: Connection refused
Then fix Elasticsearch master to insert again.
Insertions are blocked.
If bulk concurrent requests = 1 there is no issue.
Note that same test does not fail with deprecated bulk processor
