luoyuxia opened a new issue, #129:
URL: https://github.com/apache/paimon-rust/issues/129
## Parent Issue
Part of #124 (support partitioned table)
Depends on #128 (fix TableScan partition paths)
## Background
`TableRead::to_arrow()` explicitly rejects partitioned tables:
```rust
// read_builder.rs:88-95
if !self.table.schema.partition_keys().is_empty() {
return Err(Error::Unsupported {
message: format!(
"Reading partitioned tables is not yet supported. Partition
keys: {:?}",
self.table.schema.partition_keys()
),
});
}
```
Once TableScan generates correct partition paths (#128), the ArrowReader
will be able to read data files under partition directories without additional
changes (since it reads from the `bucket_path` in DataSplit).
## What needs to be done
1. **Remove the partition key check** in `TableRead::to_arrow()` (lines
88-95 of `read_builder.rs`)
2. **Verify ArrowReader works** with the corrected paths — it reads
`{bucket_path}/{file_name}`, so as long as `bucket_path` is correct, no
ArrowReader changes should be needed
## Affected files
- `crates/paimon/src/table/read_builder.rs` — `TableRead::to_arrow()` method
