Hi,  
I noticed regular peaks in indexing rate every night between 03:00 and 04:00. I think it's something like cluster maintenance, rolling out indices, moving indices from one node to another, but I don't know what it is exacly and I would like to know what happens. Can someonene share knowledge with me?
