title PolyJDBC

PolyJDBC

PolyJDBC is a polyglot, lightweight wrapper around standard JDBC drivers with schema inspection/creation capabilities.

Target

PolyJDBC primary target are libraries that need light and cross-platform JDBC persistence. Hibernate is great, but it leaves little place for end-user customization, which is important when offering a library. It is also quite heavy. PolyJDBC size is only 97kB, no dependencies except for slf4j logging API.

Is anyone using it?

Apart from internal projects, there are two OpenSource projects currently using PolyJDBC:

Features

  • polyglot (or better poly-dialect? multiple DB dialect support, including id generation strategies)
  • transaction-oriented
  • resources (Statements, ResultSets) are managed inside transaction scope
  • intiutive transaction commit/rollback support
  • option to leave transaction management to external framework (i.e. Spring)
  • DDL operation DSL (CREATE TABLE/INDEX/SEQUENCE with constraints, DROP *)
  • SQL query DSL (INSERT, SELECT, UPDATE, DELETE)
  • lightweight
  • schema inspection (table/sequence exists?)
  • schema alteration

Supported database engines

  • H2
  • PostgreSQL
  • MySQL
