Hi Guys,

I was trying to figure out what all activities elasticsearch performs when it boots up. So lets say, I have a single node with 5 indexes. The node was shut down and then started.

What all steps are performed?  
How indexes are loaded into the memory?  
Is there a way to prioritize which index will load first into the memory?

I couldn't find any blog/document to put some light on this process. Any links appreciated here.

Thanks
