One problem is that application development engineers and database administrators’operations be‐ come exceptionally laborious, when facing Carte‐ sian product correlation will not appear in the multi‐table correlating query, so the query efficiency will increase greatly. Take this one for example, if SQL is: SELECT i.* FROM t_order o JOIN t_order_item sharding algorithm is: ds${id % 10} Or ds$->{id % 10} Distributed Primary Key Motivation In the development of traditional database software, the automatic sequence generation technology is a basic requirement

For example, t_order and t_order_item are both sharded by order_id, and use order_id to correlate Cartesian product correlation will not appear in the multi‐tables correlating query, so the query efficiency will increase greatly.

one of the simplest persistence frameworks available today. Fast Development − MyBatis does all it can to facilitate hyper-fast development. Portability − MyBatis can be implemented for nearly any language You would have to set up a proper environment for MyBatis before starting off with the actual development work. This chapter explains how to set up a working environment for MyBatis. MyBatis Installation is how you can use an environment tag in practice −
