Overview

The job of the Load Context is to support secondary loading queries (both eager and lazy) with batch loading (to avoid N + 1) and propagating key query execution context from the origin query to the secondary queries.

Batch loading

The Load context provides the batch loading mechanism. This solves the N + 1 issue for Ebean. As such it is one of the most important internal features of Ebean ORM.

Propagate query context

When secondary queries load additional parts of the object graph Ebean propagates key query execution context from the origin query to the secondary queries including:

• History asOf timestamp or version timestamps
• Draftable state
• Soft delete state
• Read auditing state
• Document store state
• Read only state
