orm-fetch-dsl | A DSL for eagerly fetching columns with ORM queries

orm-fetch-dsl is a Java library. orm-fetch-dsl has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can download it from GitHub, Maven.

What is ORM-Fetch-DSL? === A Groovy DSL for instructing ORM queries which columns to fetch eagerly. Most ORM implementations operate with partial objects - the same object can be re-used in multiple queries, but it is fetched partially - every query specifies which fields of the object (mapped to columns in the table) to fetch. Access to any field that wasn’t explicitly pre-fetched will cause the ORM to load it lazily from the DB. To prevent this lazy loading, the ORM has to be instructed up front which columns to fetch for every query. The eager-fetch configuration can become very deep (for tables with lots of joins) and cumbersome to maintain, and this tries to alleviate the strain a bit. Disclaimer === This is admittedly geared towards JPA-style ORMs, or any ORM which represents tables as entity classes that store database metadata as annotations on the fields themselves. Structure --- There is a core module 'fetch-dsl-core', which is independent of any specific ORM implementation. It simply translates the DSL into a parent-child tree. ORM-specific implementations are expected to know how to apply this relation to their queries.
