Use DB3 as a backup of centralized MySQL

For most web2 developers, you can start from one of the scenarios to learn and understand the benefits of decentralized databases: you can put a decentralized database behind a centralized database (such as MySQL) as a hot backup, In this way, the business side can use DB3 to back up the existing business without any intrusiveness.
For most web3 developers, it is an obligatory mission to continuously optimize the architecture to make the dapp more decentralized. The existence of a centralized database determines that this so-called decentralized dapp is a bit superficial. Now, we can connect our decentralized database as a hot backup to the centralized database that is currently running on your project.
The backup tools are built on the way, and we will release them in a few days. The communication is welcome.
