Python Engine Changelog

v10 (2024-4-2) - Backend supported version: 12.0

Python engine version supporting Clover Club 12.0.X backend, with updated minor versions of dependencies

Changed

• Updated minor versions of dependencies

v9 (2024-03-01) - Backend supported version: 11.1

This is the official version supporting Bee’s Knees 11.1 backend.

It replaces the faulty append_xxx methods with more accurate update_xxx.

These methods were relying on a REST API endpoint with a silent faulty behavior regarding duplicate keys columns. They could replace data instead of appending them if usage of unique keys/index was not handled.

Support for the methods is removed immediately as the faulty behavior is hard to detect, easy to trigger and impossible to fix properly.

Users should switch to the corresponding update_xxx methods introduced in this release.

Documentation now available at https://developer.pricefx.eu/pricefx-api/.

This release upgrades Python version to 3.10 and changes the API vocabulary to be more consistent with the backend one. This is a major breaking change.

Added

• Data Source, Datamarts, Model tables and Model attachments collection can now be indexed by name or by index (MR45).
   pfx.get_context().datasources().get_by_name("my_data_source") can now be written pfx.get_context().datasources()["my_data_source"]

• pynndescent library to datascience and neural images (MR51).

Changed

• Uses Python 3.10 (MR48).

• Improved backend vocabulary consistency by renaming API parameters.
  Warning: this involves many breaking changes if you were referring to these parameters by name when calling the corresponding methods (MR38).

  • Mainly id or uniqueid renamed to typedid and jst renamed to jst_id when relevant.

  • Refer to the API documentation for more information.

• When a backend exception occurs, the entire exception stack trace is printed in the job messages instead of the exception message only (MR47).

v1 (2022-12-20) - Backend supported version: 9.4

First version of the pricefx-python-engine.
