In computing, I/O module is the exchange of information
between the brain (CPU/memory combo) of computer and
Sharding algorithms are used to distribute slices to data
nodes, which is the core business in distributed databse. In
our system, we implement some of the most common
sharding algorithms, which can meet most of the business
requirements. Of course, the user can define the unique
sharding algorithm for special business and you just need to
modify some parts of the configuration file. There are some
examples as follows
