英文:
Indexing thousands of records into Elasticsearch using Index API synchronous is right approach?
问题
我正在尝试将超过7000条记录索引到Elasticsearch中。我将从JSon数组中选择所有这些记录，基于其长度，我将遍历数组，然后使用IndexRequest API逐一将记录索引到Elasticsearch中。由于我对Elasticsearch还不熟悉，我想确认这是否是正确的方法。我在下面提供了我的代码。
for (int i = 0; i < odsData.size(); i++) {
IndexRequest request = new IndexRequest(ConstantsHelper.INDEX_NAME + strDate);
request.id();
String jsonString = odsData.get(i).toString();
request.source(jsonString, XContentType.JSON);
IndexResponse indexResponse = client.index(request, RequestOptions.DEFAULT);
}
这种方法是否正确？另外，我想在索引完成后检查数组中的记录数是否与已在Elasticsearch中索引的记录数匹配？
英文:
I am trying to index more than 7000 records into elasticsearch. I will pick all those records from JSonarray based on it's length i will loop through the array and i will index records one by one into elasticsearch using Indexrequest API. Since i am new to Elastisearch i wanted to confirm is this right approach. I have given my code below.
for (int i = 0; i < odsData.size(); i++) {
IndexRequest request = new IndexRequest(ConstantsHelper.INDEX_NAME + strDate);
request.id();
String jsonString = odsData.get(i).toString();
request.source(jsonString, XContentType.JSON);
IndexResponse indexResponse = client.index(request, RequestOptions.DEFAULT);
}
In this a right approach? Also i wanted to check No of records in array and no of records indexed in the Elasticsearch are matching once indexing gets completed?

没问题，这应该可以正常工作，但处理过程会比较慢。此外，还有一个批量索引的 API，可以一次性索引多个文档，速度非常快。链接
英文:
Yes that should work fine, but it will be a slow process. There is also a bulk indexing API that you can use to index multiple documents at once which is very fast. Link
