But this also let me consider the problem of paging performance, in the case of different data volume, different pagin

We are going to perform a simple test on reading and writing MongoDB, Redis, and Tokyo Tyrant. To perform a fair test, we need to understand the implementation mechanism behind them. Below are some comparisons:Comparison of storage implementation:* Memory File Image (Memory-File Mapping) Redis, MongoDB* File + Cache Tokyo Tyrant* Memory: Redis, Tokyo TyrantKey/Value index format:* B + Tree: MongoDB, Tokyo Tyrant* Hash Table: Redis, Tokyo Tyrant* Fixed Length: Tokyo TyrantFrom the above
