Hello! As far as my understanding goes, there's no distinction in Ignite between "data pages" and "index pages" All pages in durable memory are parts of "B+ tree" and are holding both data and references to downward branches in other pages.
I'm not sure it had to load all the pages. Maybe only ones that needed applying updates from WAL? Which, in case of infrequent checkpoints, were plentiful? I expect most persistent databases would have non-trivial startup times when full with data. Regards, -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
