1.bulk操作

bulk操作的api

  XContentBuilder xContentBuilder1 = XContentFactory.jsonBuilder()                .startObject().field("name","1234").endObject();        XContentBuilder xContentBuilder2 = XContentFactory.jsonBuilder()                .startObject().field("name","4321").endObject();        XContentBuilder xContentBuilder3 = XContentFactory.jsonBuilder()                .startObject().field("name","9999").endObject();        BulkRequestBuilder bulk = client.prepareBulk();        bulk.add(new IndexRequest(index,type,"3").source(xContentBuilder1));        bulk.add(new IndexRequest(index,type,"4").source(xContentBuilder2));        bulk.add(new IndexRequest(index,type,"5").source(xContentBuilder3));        BulkResponse responses = bulk.get();        Iterator<BulkItemResponse> iterator = responses.iterator();        for (BulkItemResponse respons : responses) {            System.out.println(respons.getResponse());        }

bulkprocess的方式

    BulkProcessor build = BulkProcessor.builder(client, new BulkProcessor.Listener() {            @Override            public void beforeBulk(long l, BulkRequest bulkRequest) {                System.out.println("执行前");            }            @Override            public void afterBulk(long l, BulkRequest bulkRequest, BulkResponse bulkResponse) {                System.out.println("执行后");            }            @Override            public void afterBulk(long l, BulkRequest bulkRequest, Throwable throwable) {                System.out.println("处理异常");            }        })                .setBulkActions(10000)//设置bulk执行数                .setBulkSize(new ByteSizeValue(5, ByteSizeUnit.MB))//设置bulk处理的大小                //设置超时和重调次数                .setBackoffPolicy(BackoffPolicy.exponentialBackoff(TimeValue.timeValueMillis(100), 3))                .setConcurrentRequests(1)//设置并发量                .build();//            build.add()  这里添加批处理的操作              build.flush();              build.close();
