frankliee opened a new issue, #1488:
URL: https://github.com/apache/iceberg-python/issues/1488
### Apache Iceberg version
None
### Please describe the bug 🐞
the bad code : load table in the sub process
```python
from multiprocessing import Process
worker_num = 2
def worker(tbl):
arr = tbl.scan().to_arrow()
print(arr)
from pyiceberg.catalog import load_catalog
catalog = load_catalog("mycatalog")
tbl = catalog.load_table("db.table")
workers = [Process(target=worker, args=(tbl, )) for worker_id in
range(worker_num)]
[p.start() for p in workers]
[p.join() for p in workers]
```
the good code: load table in the main process
```python
from multiprocessing import Process
worker_num = 2
def worker():
from pyiceberg.catalog import load_catalog
catalog = load_catalog("iceberg_catalog")
tbl = catalog.load_table("dla_test.words")
arr = tbl.scan().to_arrow()
print(arr)
workers = [Process(target=worker, args=()) for worker_id in
range(worker_num)]
[p.start() for p in workers]
[p.join() for p in workers]
```
