RyanLin5967 opened a new issue, #4188:
URL: https://github.com/apache/iceberg-python/issues/4188
### Apache Iceberg version
0.12.0 (latest release)
### Please describe the bug 🐞
Currently, a commit retry writes the added manifest under the refreshed
default spec, so a file partitioned by `p` gets its `p` value recorded as `q`
and filters on `q` prune it. A handle loaded after the spec change is correct.
```python
import tempfile
import pyarrow as pa
from pyiceberg.catalog.sql import SqlCatalog
cat = SqlCatalog("c", uri="sqlite:///:memory:",
warehouse=f"file://{tempfile.mkdtemp()}")
cat.create_namespace("ns")
row = lambda x, p, q: pa.table({"x": [x], "p": [p], "q": [q]})
t = cat.create_table("ns.t", schema=row(1, 5, 50).schema)
with t.update_spec() as u:
u.add_identity("p")
b = cat.load_table("ns.t")
with b.update_spec() as u:
u.remove_field("p")
u.add_identity("q")
b.append(row(2, 6, 60))
t.append(row(3, 7, 70))
print(cat.load_table("ns.t").scan(row_filter="q ==
70").to_arrow()["x"].to_pylist())
# [], should be [3]
# t's commit retried after b's append, and its file was recorded under b's
spec as q=7
```
If the new spec has a different number of fields, the append raises
`IndexError`, and `dynamic_partition_overwrite` mislabels its file the same way.
tested on pyiceberg 0.12.0 and main
