I use mmapfs to write data, but I want to change to niofs, need to rewrite the data? Then how to view index.store.type?
No, there's no need to rewrite the data when changing store type.
It is an index-level setting so you can view it using the index settings API.
Thanks David for your quick response!
after adding 'index.store.type: niofs' to the
config/elasticsearch.yml .How can I confirm that it has changed?
GET _nodes/settings returns the static settings applied on each node.
thanks for you reply!
