Description
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
