How to verify the index is stored in memory?

Hi,

I would like to switch my ES cluster to store our index in memory. So, I've
added the following to elasticsearch.yml

index.storage.type: memory
cache.memory.small_buffer_size: 1mb
cache.memory.large_buffer_size: 10mb
cache.memory.small_cache_size: 1000mb
cache.memory.large_cache_size: 2000mb

as well as in elasticsearch.conf

wrapper.java.additional.14=-Des.index.store.type=memory

How do I verify that? Is there a REST API that I use for that?

Thanks,
Connie

Hi Connie,

Not sure if there is a more direct way, but you can check your monitoring
tool of choice and look at disk IO while querying your index, or use any of
the command-line tools like vmstat or iostat under UNIX.
