# my_custom_filesystem.py
# Implement your custom filesystem using PyArrow interfaces here
# For example:
import pyarrow as pa
class MyCustomFileSystem(pa.FileSystem):
def __init__(self):
# Initialize your custom filesystem here
pass
def open_input_file(self, path):
# Implement your open_input_file method
pass
# ... other methods ...
```
```
# my_path_to_filesystem.pyx
# Import required PyArrow modules and symbols from the .pxd files
from pyarrow.includes.common cimport *
from my_custom_filesystem cimport MyCustomFileSystem
# Your Cython code using PyArrow with your custom filesystem goes here...
# For example:
cdef void my_function():
cdef FileSystem fs = MyCustomFileSystem()
# Use the PyArrow API with your custom filesystem
# For example:
cdef File file = fs.open_input_file("my_file.txt")
# ... other PyArrow operations with the custom filesystem ...
```
