My goal is to do insert and update multiple documents in ElasticSearch using ElasticsearchRepository.

public interface EmployeeInfoRepository extends ElasticsearchRepository<EmployeeInfo, String> {

}

However, whenever I call saveAll(entities), the number of document is unchanged but it creates new indexes for those entities.

employeeInfoRepository.saveAll(employeeInfos);

If I insert 1000 elements, at first it will have 1000 docs and 1000 indexes, which is what I expected. Then I call saveAll two more times, it still has 1000 docs but now the number of indexes increases to 3000.

How can I update it properly?

It would be the best if it's just as easy as calling saveAll and the rest is handled by SpringBootData ElasticSearch.

Turns out the index_total just count the number of indexed items. The main thing here is the storage size keeps increasing after each saveAll. At this point I have some assumptions:

• Because of the snapshot for each document
• Because requests are cached

The size of the indices directory actually keeps increasing, now I need to know how the inverted index are stored.
