Hello - Can someone help me understand what the OPERATIONS metrics below signify? we are facing read timeouts whilst POSTING to this specific index. We noticed a lot of Flush/Refresh/Merges (see below) on this index! Could they be the cause of the timeouts? also - its been like this for a few hours - any suggestions on how to "Cool" down this index to make it serviceable for writes?

Are you by any chance performing a lot of reasonably frequent updates? Which version are you on?

yes - but its a one time bulk Write to this specific index. Version 5.5 - am curious if the writes die down - would this operations settle down?

How frequently are you updating a single document? What is your average document size?

we never update a document. its only inserts and its only a few KB in an extreme case. But we did do a large number inserts.  
FYI I did check this morning and the stats haven't changed. The index is NOT in use in any read/write capacity for now. Are these stats a false negative?
