luoyuxia opened a new issue, #130:
URL: https://github.com/apache/paimon-rust/issues/130
## Parent Issue
Part of #124 (support partitioned table)
Depends on #126, #127, #128, #129
## Background
Currently, the only integration test (`read_log_tables.rs`) tests reading a
non-partitioned, non-pk append-only table. We need integration tests
specifically for partitioned tables.
## What needs to be done
1. **Prepare test fixtures**
- Create a partitioned table warehouse fixture (or provide instructions
to generate one using Java Paimon / Flink)
- Tables should cover:
- Single partition key (e.g., `dt STRING`)
- Multiple partition keys (e.g., `dt STRING, hr INT`)
- Different partition key types (String, Int, Date)
2. **Integration tests**
- Read a single-partition-key table, verify all partitions are returned
with correct data
- Read a multi-partition-key table
- Verify partition column values are correct in the returned RecordBatches
3. **Unit tests**
- Test `TableScan.plan()` on a partitioned table: verify DataSplits have
correct `bucket_path` with partition segments
- Test that the number of splits matches expected `(partition, bucket)`
groups
## Affected files
- `crates/integration_tests/tests/` — new test file(s)
- `crates/paimon/tests/fixtures/` — possible new fixtures
