    • getOffsetOptimizingThreshold

      public int getOffsetOptimizingThreshold()
      For RDBMS, pagination is slow if `offset` is large, especially for MySQL. If `offset` >= $thisArgument 
      
  select t.* from Table t ... limit ? offset ?
      will be automatically changed to 
      
  select t.* from (
      select
          t.id as optimized_core_id_
      from Table t ... limit ? offset ?
  ) optimized_core_
  inner join Table as optimized_
      on optimized_.optimized_core_id_ = optimized_core_.optimized_core_id_
      返回:
      An integer which is greater than 0

    • isForeignKeyEnabledByDefault

      public boolean isForeignKeyEnabledByDefault()
      This configuration is only useful for JoinColumn of local associations (not remote associations across microservice boundaries) whose `foreignKeyType` is specified as `AUTO`.Its value indicates whether the foreign key is real, that is, whether there is a foreign key constraint in the database.

      In general, you should ignore this configuration (defaults to true) or set it to true.

      In some cases, you need to set it to false, such as
      • Using database/table sharding technology, such as sharding-jdbc
      • Using database that does not support foreign key, such as TiDB

    • isSaveCommandPessimisticLock

      public boolean isSaveCommandPessimisticLock()

    • getExecutorContextPrefixes

      @Nullable public Collection<String> getExecutorContextPrefixes()
      If this option is configured, when jimmer calls back `org.babyfish.jimmer.sql.runtime.Executor.execute` before executing SQL, it will check the stack trace information of the current thread. However, these stack traces have too much information, including infrastructure call frames represented by jdk, jdbc driver, jimmer, and spring, and the business-related information you care about will be submerged in the ocean of information. Through this configuration, you can specify multiple package or class prefixes, and jimmer will judge whether there are some call frames in the stack trace whose class names start with some of these prefixes. If the judgment is true, jimmer believes that the current callback is related to your business, and the `ctx` parameter of `org.babyfish.jimmer.sql.runtime.Executor.execute` will be passed as non-null. If the SQL logging configuration is enabled at the same time, when a SQL statement is caused by the business you care about, the business call frame will be printed together with the SQL log.
