----------------------------------
Summary: Quidem test support TopDownGeneralDecorrelator
Key: CALCITE-7342
URL: https://issues.apache.org/jira/browse/CALCITE-7342
Project: Calcite
Issue Type: New Feature
Components: core
Affects Versions: 1.41.0
Reporter: Zhen Chen
Assignee: Zhen Chen
We recently merged the new TopDownGeneralDecorrelator (CALCITE-7031).
Currently, configuration has only been added to RelOptFixture, but end-to-end
testing of Calcite cannot be performed using the new Decorrelator. To perform
end-to-end testing, we might need a configuration to enable the new
Decorrelator (it's disabled by default). This is necessary to advance the
further development and validation of the new Decorrelator, such as
implementing MARK JOIN in CALCITE-7315 in the future, or assuming the new
Decorrelator can truly become a production-ready option for users. All of this
requires thorough testing, so this Jira implementation aims to provide a quidem
test example that supports the new Decorrelator to support future development.
However, this will introduce a configuration parameter to enable the new
Decorrelator, which may remain for a considerable period until the new
Decorrelator reaches production-ready status.
The current Jira idea is to provide a dedicated decorrelate.iq file to support
continuous iteration.
