> Need implement some data structure to store/get multiple entry versions:
> - committed value at first is stored in separate data structure (there also 
> need store related tx id to filter out data for non-finished transactions), 
> probably existing BPlusTree can be used
> - periodically need flush data for finished transaction in 'main' hash index
> - 'getAll' operation should include max 'visible' ID and list of active 
> transactions, this information should be used to find last 'visible' version 
> in 'mvcc' or 'main' index
