@zeroshade @joellubi I created a script to generate dummy data for
reproducing the issue:
```python
import polars as pl
import pyarrow.dataset as ds
import adbc_driver_snowflake.dbapi
num_rows = 10_000_000
parquet_path =
conn_uri =
lf = pl.LazyFrame({'id': range(num_rows)})
lf = lf.with_columns(pl.lit('This is just a dummy test
string.').alias(f"dummy_string_{i}") for i in range(30))
lf.sink_parquet(parquet_path)
data = ds.dataset(parquet_path)
# Splits into 83 files in 1.0 but only 4 in 1.1
with adbc_driver_snowflake.dbapi.connect(conn_uri, autocommit=True) as conn,
conn.cursor() as cursor:
cursor.adbc_statement.set_options(**{'adbc.snowflake.statement.ingest_target_file_size':
str(2**14), 'adbc.snowflake.statement.ingest_writer_concurrency': '4'})
cursor.adbc_ingest('Test', data, 'replace')
```
With ADBC 1.0.0, the data were split into 83 parquet files:
But only 4 with ADBC 1.1.0:
