Hi,
Is there a way to tell ES to open closed indices automatically on first access (search or indexing)? I can do it on the application side by looking for IndexClosedException, but this seems like a natural thing that ES should be able to do, after all ES creates new indices automatically.

Opening an index is a costly operation.
Creating a new index is not.

I agree. But they both go thru shard allocation, no? I’m assuming opening/closing small 1 shard indexes (max 100MB total size) shouldn’t be that bad.

That's still massively different to creating and allocating a completely
empty index.
