Interface LoaderOptionsStep<R extends Record>

All Superinterfaces:
LoaderSourceStep<R>
public interface LoaderOptionsStep<R extends Record> extends LoaderSourceStep<R>
The Loader API is used for configuring data loads.

Add options to for the loading behaviour. For performance reasons, you can fine-tune three different types of measures:

  • The bulk statement size. This specifies how many rows will be inserted in a single bulk statement / multi-row INSERT statement.
  • The batch statement size. This specifies how many bulk statements will be sent to the server as a single JDBC batch statement.
  • The commit size. This specifies how many batch statements will be committed in a single transaction.

Referencing XYZ*Step types directly from client code

It is usually not recommended to reference any XYZ*Step types directly from client code, or assign them to local variables. When writing dynamic SQL, creating a statement's components dynamically, and passing them to the DSL API statically is usually a better choice. See the manual's section about dynamic SQL for details: https://www.jooq.org/doc/latest/manual/sql-building/dynamic-sql.

Drawbacks of referencing the XYZ*Step types directly:

  • They're operating on mutable implementations (as of jOOQ 3.x)
  • They're less composable and not easy to get right when dynamic SQL gets complex
  • They're less readable
  • They might have binary incompatible changes between minor releases
