SQLAlchemy 0.6 Released
April 18, 2010 permalink
SQLAlchemy 0.6 is now released. This release is the culmination of well over a year of effort towards restructuring and enhancements. Highlights of SQLAlchemy 0.6 include:
- Support for Python 2.4+, Python 3, and Jython
- Decouping of DBAPI adapters and database dialects allow any number of DBAPIs to be cleanly supported.
- Support for Sybase, mxODBC, pg8000, py-postgresql, OurSQL, MySQL-Connector-Python, zxjdbc is added, including new options and capabilities for many dialects (see the compatibility chart).
- Enhancements to "eager loading", including a new "subquery" eagerload that loads all collections using a maximally efficient query-per-relationship scheme.
- An entirely new unit of work system which runs more effectively and simply, using less memory and CPU.
-
A flexible SQL compiler and execution system, now supporting RETURNING clauses when available, clause constructs for DDL elements (i.e. CREATE TABLE) and type objects, stricter SQL standard compliance where needed, and an extension system allowing the creation of new SQL constructs and open-ended extension to those provided.
-
Query result caching capability, including an example illustrating integration with Beaker.
SQLAlchemy 0.6 has already been in production usage for several months and has been tested by hundreds. Be sure to review the full list of whats new at 06Migration.
