  • Add support for primary keyless tables.
  • Unified management limit.
  • In the case of joint primary keys, the chain call scheme of OR is used to compare the primary keys one by one to delineate the data range. For example:pk1>? or (pk1=? and pk2>?) or (pk1=? and pk2=? and pk3>?)....
  • The advantages are that it supports limit, indexes, avoids data skew, and reasonably divides data ranges
