Hi,
As per the blog below, there is considerable improvement made in Elasticsearch 7.10 in data storage needs.
Save space and money with improved storage efficiency in Elasticsearch 7.10 | Elastic Blog.
In our tests as well with 7.10 , we see storage savings of 10 - 15 percent compared to the version Elasticsearch 7.0 we have been using. However this comes with a cost in performance time.
We see a similar degradation of 10% - 20% in the overall indexing time by just doing an apple to apple comparison with 7.0 based setup.
From the documents we do not see a specific configuration which can turn off the increased compression rate. We use the default from Elaticsearch now ( Did not do the best_compression) as it clearly indicates there can be more performance issues in search time.
I have the following points to clarify. Any inputs on this would be really helpful.
Is the performance degradation in Indexing expected due to the improved storage compression?
Is there a way to turn off the new compression logic?
