[jira] [Created] (ARROW-7553) Unable to free all memory allocated when creating a GArrowSchema

 Summary: Unable to free all memory allocated when creating a 
GArrowSchema
 Key: ARROW-7553
 URL: https://issues.apache.org/jira/browse/ARROW-7553
 Project: Apache Arrow
  Issue Type: Bug
  Components: C, GLib
Affects Versions: 0.15.1
 Environment: Ubuntu Focal with Linuxbrew packages installed
Reporter: Mike Pontillo


I was not able to run the test code in [this 
gist|https://gist.github.com/mpontillo/cfbe7ebbf0b0f2acf31063512439bde7] (and 
corresponding [GitHub issue|https://github.com/apache/arrow/issues/6164]) 
without encountering a memory leak via {{garrow_schema_get_type_once}} 
(according to {{valgrind}}):

{code:java}
24 bytes in 1 blocks are possibly lost in loss record 192 of 486
   at 0x4A391AF: realloc (vg_replace_malloc.c:836)
   by 0x53B5D97: g_realloc (gmem.c:164)
   by 0x5128108: type_node_any_new_W (gtype.c:502)

   by 0x4CB5860: garrow_schema_new (in

   by 0x401219: main (main.c:13)
{code}

I'm not positive if this is an actual bug in {{apache-arrow-glib}} or if my 
test code is incorrect, but I thought I would file an issue here (in addition 
to my question posted as a GitHub issue) for greater visibility.

It looks like the {{realloc}} call actually happens via {{glib}}; is this a 
one-time type registration that isn't expected to be cleaned up until the 
process exits? (I couldn't find a reference to {{garrow_schema_get_type_once}} 
in the {{arrow}} code.) I wanted to be certain, since I expect to use 
{{arrow-glib}} within a long-running process.

Tests that rely on timing are pretty tough to do on public CI. We should 
consider moving this somewhere that doesn't run on CI.

We wrap the examples in {{\donttest{}}} so that they aren't run on CRAN, where 
the Arrow C++ library isn't present and thus the examples would error. But 
locally and on our CI, where we *are* testing with the C++ library, we should 
run the examples to ensure that they're valid. (As ARROW-7543 revealed, they 
weren't.)

[jira] [Created] (ARROW-7547) [C++] [Python] [Dataset] Additional reader options in ParquetFileFormat

 Summary: [C++] [Python] [Dataset] Additional reader options in 
ParquetFileFormat
 Key: ARROW-7547
 URL: https://issues.apache.org/jira/browse/ARROW-7547
 Project: Apache Arrow
  Issue Type: Improvement
  Components: C++ - Dataset, Python
Reporter: Joris Van den Bossche


[looking into using the datasets machinery in the current python parquet code]

In the current python API, we expose several options that influence reading the 
parquet file (eg {{read_dictionary}} to indicate to read certain BYTE_ARRAY 
columns directly into a dictionary type, or {{memory_map}}, {{buffer_size}}).

Those could be added to {{ParquetFileFormat}}.

Per discussion https://github.com/apache/arrow/pull/5945#discussion_r365108806.

In ARROW-7284, we write a simple method to concat vectors. However, ARROW-7073 
is about to concat vector values efficiently, after this PR merged, we should 
use this new implementation in {{ArrowReader}}.

 Project: Apache Arrow
  Issue Type: Bug
  Components: C++ - Dataset
Reporter: Joris Van den Bossche


I assume it is an issue on the C++ side of the datasets code, but reproducer in 
Python. 

I create a small parquet file with a single column of dictionary type. Reading 
it with {{pq.read_table}} works fine, reading it with the datasets machinery 
hangs when scanning:

{code:python}
import pandas as pd
import pyarrow as pa
import pyarrow.parquet as pq

df = pd.DataFrame({'a': pd.Categorical(['a', 'b']*10)})
arrow_table = pa.Table.from_pandas(df)

filename = "test.parquet"
pq.write_table(arrow_table, filename)

from pyarrow.fs import LocalFileSystem
from pyarrow.dataset import ParquetFileFormat, Dataset, 
FileSystemDataSourceDiscovery, FileSystemDiscoveryOptions

filesystem = LocalFileSystem()
format = ParquetFileFormat()
options = FileSystemDiscoveryOptions()

discovery = FileSystemDataSourceDiscovery(
filesystem, [filename], format, options)
inspected_schema = discovery.inspect()
dataset = Dataset([discovery.finish()], inspected_schema)

# dataset.schema works fine and gives correct schema
dataset.schema

scanner_builder = dataset.new_scan()
scanner = scanner_builder.finish()
# this hangs
scanner.to_table()
{code}
