Pustike Persist

Persist is an object based persistence library. Using a simple configuration and annotation based entity mapping, it provides features like schema generation, sql query api to insert / update / delete objects and a fluent data finder api.

Using Java Persistence API is the standard approach to object persistence in Java based applications. And it is a comprehensive and complex API to implement and use. Using a JPA implementation for persistence can add lot of overhead to small/medium sized applications. So, Pustike Persist provides a simple api to perform common SQL queries using object metadata built using JPA like annotations.

Following are some of its key features:

  • Repository configuration using dataSource and schema metadata
  • Entity mapping to database table and fields to columns using annotations
  • Database schema generation with indexes, foreign keys, constraints, etc using the mapping tool
  • Allows field group definitions per entity to fetch or update only the required data
  • Insert single/list of objects into database in batch and support update on conflict using excluded rows
  • Update single/multiple objects in the database using the specified field group
  • Select row data as object with the given identity and option to select them for update with lock
  • Delete single/multiple objects
  • A fluent Finder API to construct sql queries and fetch result data as objects
  • Supported databases: PostgreSQL
  • Requires Java 11 and has no external dependencies (~60kB in size)

Documentation: Latest javadocs is available here.

Todo:

  • Write unit tests using test container
  • More detailed documentation
  • Support readOnly transactions
  • Allow multiple schema definitions per repository
  • Override field name when using field@fgName instead of adding both
  • Finder API - add fetch(String fgName) as a method to reduce the number of overloaded fetch methods
  • MappingTool - create ForeignKey column based on the type of @Id column
  • MappingTool - if existing field metadata is changed, compare with the database and show warnings
  • Add support for Composite primary key
  • Implement L1 Cache to avoid creating same object multiple times
  • Support more databases (MySQL, H2, HSQLDB, Derby)
