I am performing some test on tuning disk space for Elasticsearch index. I found some good tips to compress the elasticseach index size. Especially, If your use case is only show dashboard in Kibana. During these indexes sizing analysis I observed
best_compression gives me
21% gain in disk space.
So my question is here,
Is there any drawback of using best_compression in elasticsearch?
If not, then why Elasticsearch not enable
best_compression as a default
index.codec instead of LZ4 compression ?
I tried to find answer to these questions, but I couldn't succeed. Can you please help me to understand it better. Thanks.
