I have a non-prod cluster that I use to run tests. I took a snapshot of my prod cluster data and restored it into this non-prod cluster which created the two indices that I have in production. However when I GET _cat/indices?v
on this test cluster the docs.deleted
value (which is non-zero for both indices) for those two indices hasn't changed ever. Any idea why this is happening? These indices have not been used since they were created, so could this lack of activity on the indices be the reason?
Are you deleting docs?
No I'm not deleting docs. I'm not even using the indices yet, I just set them up two days ago and noticed today that the docs.deleted
value has not changed for either index.
Then I wouldn't worry too much.
Deletes can happen due to updates as well. But if you're not doing either it's not a concern.
Thanks for your reply. I'm trying to understand how docs.deleted
works. Is that value staying the same because the indices are idle(i.e I'm not using them yet)? According to this, There is nothing you need to do to enable merging. It happens automatically while you are indexing and searching
. So since my indices are idle, automatic merges are not happening?
It'll change when documents are updated or deleted. You can still read from or write to an index and that number will not change. It doesn't mean the index is idle.
By "idle" I meant that I'm not using those indices yet. I'm still writing the client code that will interact with them.

I see. I was expecting docs.deleted
to decrement. I thought merging would've been happening since the creation of the indices.
Can you share the output from the cat call?

You can try a force merge and see if that changes it?
Yes, force merge changed the doc.count
s to zero, but I'm still confused as to why they never changed prior to the merge.
