Sascha Hofmann created ARROW-6046:
-------------------------------------
Summary: Slice RecordBatch of String array with offset 0
Key: ARROW-6046
URL: https://issues.apache.org/jira/browse/ARROW-6046
Project: Apache Arrow
Issue Type: Bug
Components: C++, Python
Affects Versions: 0.14.1
Reporter: Sascha Hofmann
We are seeing a very similar bug as in ARROW-809, just for a RecordBatch of
strings. A slice of a RecordBatch with a string column and offset =0 returns
the whole batch instead.
{code:java}
import pandas as pd
import pyarrow as pa
df = pd.DataFrame({ 'b': ['test' for x in range(1000_000)]})
tbl = pa.Table.from_pandas(df)
batch = tbl.to_batches()[0]
batch.slice(0,2).serialize().size
# 4000232
batch.slice(1,2).serialize().size
# 240
{code}
