Apparatus and Method for On-Demand In-Memory Database Management Platform

A method for implementing a dynamic replication in a memory or non-memory based block storage system storing data, said block storage system may include one or multiple of storage servers, comprising steps of:

• providing one or multiple replication blocks for a first block in said block storage system, and said replication blocks replicate partial of whole data of said first block;
• wherein accessing to said first block may be directed to said replication blocks for data access.

A method for implementing a block neighborhood scheme in a memory or non-memory based block storage system storing data, and said block storage system having a plurality of blocks, comprising steps of:

• defining a neighborhood relationship criteria among blocks;
• remembering neighbor blocks of a first block, and said neighbor blocks satisfying said neighborhood relationship criteria with said first block;
• wherein blocks that are used for data access may be stored in a memory or non-memory based backup or secondary system in said block storage system.

A memory-based on-demand database system having a plurality of blocks of memory for data operation and storage, comprising:

• means for loading a database partially or in whole from a secondary system into said memory blocks for data operation;
• means for unloading a said database from said memory blocks to said secondary system.
