enable preload hot data in memtable? #198

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
recently use leveldb as cache. everyday i have to load new data to leveldb. 
this is my logic:

close old db;
open new db;

this is the problem：
after open new db, when new query arrives, it can not hit the new db's cache.

is there any way to preload hot day into leveldb?

many thansk~
