I am running an instance of Elastic Cloud via the offered AWS facility.
I am saving a large amount of documents to the cluster and starting to reach the max capacity for storage.
When I reach a certain point the indexes will go into READ ONLY mode (which is expected). However, out of curiosity I do a "Full restart. All instances restart simultaneously." When they restart, a significant amount of space becomes available and the indexes are no longer read only.
The document counts in the indexes do not change.
So why does a full restart clear space in the storage?
I dont know if it makes any difference, but I have "index.refresh_interval": "-1" on all my indexes.
Thanks,
Matt
