Reimporting

pykx.reimporter

KDB-X Python reimport helper module.

KDB-X Python uses various environment variables to monitor the state of various modules initialization. This is required to manage all of the different modes of operation, however it can cause issues when attempting to reimport KDB-X Python within a spawned subprocess.

This module provides a mechanism to allow users to safely reimport KDB-X Python within spawned subprocesses without having to manually manage any of these internal environment variables.
