### Please describe the bug 🐞
Hey,
I have a large arrow table that I want to append to a partitioned iceberg
table.
I'm working locally with dockers and I'm using the
tabulario/iceberg-rest:1.6.0 as my rest catalog.
To avoid OOMs, I'm splitting the arrow table into chunks. When using regular
appends everything works as expected. However, I want to append all data in a
single transaction. I have this code that does that:
```python
with table.transaction() as tx:
for offset in range(0, data.num_rows, MAX_APPEND_CHUNK_SIZE):
data_slice = data.slice(offset, MAX_APPEND_CHUNK_SIZE)
logger.info(f'Writing batch of {data_slice.num_rows}
with offset {offset} to table {table.name()}')
tx.append(data_slice)
tx.commit_transaction()
```
The table is empty and was created in a different task.
I get the following error - CommitFailedException: Requirement failed:
branch main was created concurrently.
When retrying I get this error pyiceberg.exceptions.CommitFailedException:
CommitFailedException: Requirement failed: branch main has changed: expected id
4547037169132709864 != 132570956257248456.
Any help would be appreciated,
Thanks!
