Good article about In-Memory Data Grids on Cubrid’s blog by Ki Sun Song.
The features of IMDG can be summarized as follows:
- Data is distributed and stored in multiple servers.
- Each server operates in the active mode.
- A data model is usually object-oriented (serialized) and non-relational.
- According to the necessity, you often need to add or reduce servers.
Even if you don’t read it all, but plan to use an IMDG solution, the first two questions you want to ask your vendor are: what the approach you are proposing to deal with the limited memory capacity and what’s the strategy for reliability. You’ll get good answers from well established products, but these answers are not necessarily the ones that provide the exact requirements your solution will need.
