----------------------------
Summary: [C++] Better handling when TZDB is unavailable
Key: ORC-1661
URL: https://issues.apache.org/jira/browse/ORC-1661
Project: ORC
Issue Type: Improvement
Components: C++
Reporter: Gang Wu
Assignee: Gang Wu
When /usr/share/zoneinfo is unavailable and TZDIR env is unset, creating C++
ORC reader will crash on Windows. We need to better deal with this case. See
context from the Apache Arrow community:
[https://github.com/apache/arrow/issues/36026] and
[https://github.com/apache/arrow/issues/40633]
We could perhaps do following things:
* Make sure it does not crash when TZDB is missing (on Windows). The
prerequisite is to enable running C++ unit tests on Windows.
* More TZDB search locations. (e.g. $CONDA_PREFIX/usr/share/zoneinfo)
* Do not eagerly reading TZDB when timestamp types are not required.
* Add a runtime config to set TZDB location.
* Ship TZDB with the ORC library while building on Windows?
