> A "future delta partition leak" issue can be consistently reproduced: a
query for `03:40` incorrectly returns `[7,1,7,20250810,03:40]` (which
corresponds to `03:45`). The root cause lies in the delta range planning logic
near `ChainGroupReadTable.java:445`; the test case
`SparkChainTableITCase.java:2473` included in the PR fails as a result.
Hi @JingsongLi,
Thank you very much for your continued patience and attention to this PR.
Give a summary for this PR:
- the main computational framework remains unchanged in
`ChainTableUtils.getDeltaPartitions`.
- `PartitionTimeResolver` currently calculates the step size based on the
smallest time unit controlled by the pattern variables via `extractMinStep()`.
- `resolvePartitionValues(...)` converts a `LocalDateTime `back to partition
column values
- `parsePartitionValues(...)` still delegates to
`PartitionTimeExtractor.extract(...) `to parse `partitionValues` into
`LocalDateTime`.
Could you please rerun the failing test with the following command:
```
mvn test -pl paimon-spark/paimon-spark-ut -am -Pfast-build -Pspark3 \
-DwildcardSuites=none \
-DfailIfNoTests=false \
-Dtest=SparkChainTableITCase#testChainTableWithMinuteLevelPartitions
```
