Changes for version 0.03

  • Added an inflate and deflate mechanism to memcached caching. When objects are stored in memcached, they are now deflated to a hash reference containing only the column values; retrieving the object from memcached automatically inflates the object to the full representation. Classes can override inflate and deflate to store additional information in the memcached representation that's kept automatically up-to-date.
  • Added a SimplePartition driver, which helps to make partitioning, well, simpler. Still to come: documentation and a tutorial on partitioning.
  • Many, many bug fixes and improvements to the caching drivers.
  • Added detection of changed columns, such that only columns that have been changed are updated in an UPDATE statement.
  • Added a clear_cache method to the D::O::D::Cache::RAM class.
  • Added cross-DBD error handling, which maps local error codes to error constants in Data::ObjectDriver::Errors. The list of supported errors is pretty miniscule thus far (just one), but will be expanded as needed.
  • Added support for query profiling (Data::ObjectDriver::Profiler), which counts queries, calculates frequent queries, and can produce reports.
  • Added support for optional table prefixes, which simplifies setting up identical schemas in the same database.
  • Added an optional $terms argument to D::O::D::DBI->update, which can add additional terms to the UPDATE statement besides just the PK.
  • Added a D::O::D::DBI->begin_work method, and improved the commit and rollback methods.
  • Added a D::O::D::DBI->last_error method.
  • Added support for multiple JOIN clauses with a new D::O::D::SQL->add_join method.
  • Multiple OR values are now contained in an IN (...) clause rather than many joined OR clauses.
  • Added a for_update option to search, which allows constructing a SELECT ... FOR UPDATE query.
  • D::O::D::BaseObject->column is now removed and replaced with a column_func method, which returns a subroutine reference used to initialize the dynamically-created methods for each column. This allows some optimizations.
