hantangwangd opened a new pull request, #16320: URL: https://github.com/apache/iceberg/pull/16320
The metrics mode recorded in an Iceberg table reflects only the current state. That is to say, the mode may have been changed in the past, and when data was actually written earlier, the statistics were processed according to the metrics mode at that time. For example, the metrics mode might have been `truncate(5)` when the data was written, and later changed to `all`. In such a case, deciding that `min/max` aggregation on string columns can be pushed down based on the current metrics mode may lead to incorrect results. Refer to the test case in this PR for details. -- This is an automated message from the Apache Git Service.
