Abstract :

influxdb Clustered meta The module can be regarded as a simplified server , I got some enlightening thoughts about development when reading these two days .

Dependency inversion in design patterns

A more superficial statement is that the implementation of the upper layer depends on the lower layer , But the point is , What is the lower level .

meta The dependency layer of the module can be simply summarized :

-> service Layer handles network communication

-> handle Layer parsing network data , Do interface distribution

-> The interface layer depends on store Storage packaging

-> store Layers depend on raft Interface

-> raft The interface depends on raft Realization

-> raft Implementation depends on raft A consensus agreement

You can see from the above

1.  raft Consensus agreement is the foundation of kindness
2.   From this kind of tracking, more bottom layers can be extended
3.   The top depends on the bottom , Then the most important thing is the bottom !
4.   Each layer is responsible for different responsibilities , The core handled is different
