RyanLin5967 opened a new issue, #4193:
URL: https://github.com/apache/iceberg-python/issues/4193
### Apache Iceberg version
0.12.0 (latest release)
### Please describe the bug 🐞
Currently, applying `RemoveSnapshotsUpdate` sets the children's
`parent_snapshot_id` to None, so the lineage check #3512 added for an expired
exclusive start never matches and the scan raises. Java keeps the parent id,
and #3512's test removes the snapshot by hand with the parent id intact.
```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")
t = cat.create_table("ns.t", schema=pa.schema([("x", pa.int64())]))
ids = []
for x in (1, 2, 3):
t.append(pa.table({"x": [x]}))
ids.append(t.current_snapshot().snapshot_id)
scan = lambda:
t.incremental_append_scan(from_snapshot_id_exclusive=ids[0]).to_arrow()["x"].to_pylist()
print(sorted(scan()))
# [2, 3]
t.maintenance.expire_snapshots().by_id(ids[0]).commit()
print(t.snapshot_by_id(ids[1]).parent_snapshot_id)
# None, was ids[0]
print(sorted(scan()))
# ValueError: Starting snapshot (exclusive) 6945542855238032183 is not a
parent ancestor of end snapshot 6485958663478198635
# should be [2, 3]
```
tested on pyiceberg 0.12.0 and main
