Enhanced utilities and extensions for fsspec filesystems with multi-format I/O support

fsspec-utils

Enhanced utilities and extensions for fsspec filesystems with multi-format I/O support.

Overview

fsspec-utils is a comprehensive toolkit that extends fsspec with:

• Multi-cloud storage configuration - Easy setup for AWS S3, Google Cloud Storage, Azure Storage, GitHub, and GitLab
• Enhanced caching - Improved caching filesystem with monitoring and path preservation
• Extended I/O operations - Read/write operations for JSON, CSV, Parquet with Polars/PyArrow integration
• Utility functions - Type conversion, parallel processing, and data transformation helpers

Installation

# Basic installation
pip install fsspec-utils

# With all optional dependencies
pip install fsspec-utils[full]

# Specific cloud providers
pip install fsspec-utils[aws]     # AWS S3 support
pip install fsspec-utils[gcp]     # Google Cloud Storage
pip install fsspec-utils[azure]   # Azure Storage

Quick Start

Basic Filesystem Operations

from fsspec_utils import filesystem

# Local filesystem
fs = filesystem("file")
files = fs.ls("/path/to/data")

# S3 with caching
fs = filesystem("s3://my-bucket/", cached=True)
data = fs.cat("data/file.txt")

Storage Configuration

from fsspec_utils.storage import AwsStorageOptions

# Configure S3 access
options = AwsStorageOptions(
    region="us-west-2",
    access_key_id="YOUR_KEY",
    secret_access_key="YOUR_SECRET"
)

fs = filesystem("s3", storage_options=options, cached=True)

Environment-based Configuration

from fsspec_utils.storage import AwsStorageOptions

# Load from environment variables
options = AwsStorageOptions.from_env()
fs = filesystem("s3", storage_options=options)

Multiple Cloud Providers

from fsspec_utils.storage import (
    AwsStorageOptions, 
    GcsStorageOptions,
    GitHubStorageOptions
)

# AWS S3
s3_fs = filesystem("s3", storage_options=AwsStorageOptions.from_env())

# Google Cloud Storage  
gcs_fs = filesystem("gs", storage_options=GcsStorageOptions.from_env())

# GitHub repository
github_fs = filesystem("github", storage_options=GitHubStorageOptions(
    org="microsoft",
    repo="vscode", 
    token="ghp_xxxx"
))

Storage Options

AWS S3

from fsspec_utils.storage import AwsStorageOptions

# Basic credentials
options = AwsStorageOptions(
    access_key_id="AKIAXXXXXXXX",
    secret_access_key="SECRET",
    region="us-east-1"
)

# From AWS profile
options = AwsStorageOptions.create(profile="dev")

# S3-compatible service (MinIO)
options = AwsStorageOptions(
    endpoint_url="http://localhost:9000",
    access_key_id="minioadmin",
    secret_access_key="minioadmin",
    allow_http=True
)

Google Cloud Storage

from fsspec_utils.storage import GcsStorageOptions

# Service account
options = GcsStorageOptions(
    token="path/to/service-account.json",
    project="my-project-123"
)

# From environment
options = GcsStorageOptions.from_env()

Azure Storage

from fsspec_utils.storage import AzureStorageOptions

# Account key
options = AzureStorageOptions(
    protocol="az",
    account_name="mystorageacct",
    account_key="key123..."
)

# Connection string
options = AzureStorageOptions(
    protocol="az",
    connection_string="DefaultEndpoints..."
)

GitHub

from fsspec_utils.storage import GitHubStorageOptions

# Public repository
options = GitHubStorageOptions(
    org="microsoft",
    repo="vscode",
    ref="main"
)

# Private repository
options = GitHubStorageOptions(
    org="myorg",
    repo="private-repo",
    token="ghp_xxxx",
    ref="develop"
)

GitLab

from fsspec_utils.storage import GitLabStorageOptions

# Public project
options = GitLabStorageOptions(
    project_name="group/project",
    ref="main"
)

# Private project with token
options = GitLabStorageOptions(
    project_id=12345,
    token="glpat_xxxx",
    ref="develop"
)

Enhanced Caching

from fsspec_utils import filesystem

# Enable caching with monitoring
fs = filesystem(
    "s3://my-bucket/",
    cached=True,
    cache_storage="/tmp/my_cache",
    verbose=True
)

# Cache preserves directory structure
data = fs.cat("deep/nested/path/file.txt")
# Cached at: /tmp/my_cache/deep/nested/path/file.txt

Utilities

Parallel Processing

from fsspec_utils.utils import run_parallel

# Run function in parallel
def process_file(path, multiplier=1):
    return len(path) * multiplier

results = run_parallel(
    process_file,
    ["/path1", "/path2", "/path3"],
    multiplier=2,
    n_jobs=4,
    verbose=True
)

Type Conversion

from fsspec_utils.utils import dict_to_dataframe, to_pyarrow_table

# Convert dict to DataFrame
data = {"col1": [1, 2, 3], "col2": [4, 5, 6]}
df = dict_to_dataframe(data)

# Convert to PyArrow table
table = to_pyarrow_table(df)

Logging

from fsspec_utils.utils import setup_logging

# Configure logging
setup_logging(level="DEBUG", format_string="{time} | {level} | {message}")
