.. _global_context:
Global Context
==============
.. deprecated:: 3.7.0 No longer necessary as there is only one context per thread now.
If you have a single-threaded application that generates many objects,
enabling the use of the global context can provide performance enhancements.
.. warning:: The global context is not thread safe.
.. warning:: The global context maintains a connection to the database
through the duration of each python session and is closed
once the program terminates.
How to enable:
- Using :func:`pyproj.set_use_global_context`.
- Using the environment variable `PYPROJ_GLOBAL_CONTEXT`.
pyproj.set_use_global_context
-----------------------------
.. autofunction:: pyproj.set_use_global_context
