A Python package for Azure Datalake Storage adlsgen2 [abfss://] and Microsoft Fabric Lakehouse [abfss://], Google Cloud Storage [gs://bucket], AWS S3 bucket [s3://bucket] enables format detection and schema retrieval for Iceberg, Delta, and Parquet formats.It helps identify paritioned columns for parquet datasets. It also supports querying Delta, Parquet, and Iceberg formats through SQL constructs.

Project description

DataLakeSurfer

A unified toolkit for detecting, exploring, and validating data lake formats across Azure Data Lake Storage Gen2 , Microsoft Fabric Lakehouse, GCP Google Storage and AWS S3.

DataLakeSurfer lets you:

Detect whether a directory is Iceberg, Delta, or Parquet.
Retrieve normalized schema for supported formats.
Detect partition columns for Parquet datasets.
Query Delta Format Query Delta for through SQL.
Validate configuration inputs with Pydantic models.
Work seamlessly with Azure ADLS Gen2 and Fabric Lakehouse, AWS S3 and GCP GS.

ðŸš€ Installation

pip install datalakesurfer

Requirements:

Python 3.9+
pyarrowfs-adlgen2==0.2.5
adlfs==2024.12.0
azure-identity==1.17.1
azure-storage-file-datalake==12.21.0
numpy==1.26.4
pandas==1.5.3
cryptography==43.0.1

âš¡ Quick Start

Generate Token

from azure.identity import DefaultAzureCredential, ClientSecretCredential
from azure.core.credentials import AccessToken

class CustomTokenCredential():
    def __init__(self):
        self.credential = DefaultAzureCredential()

    def get_token(self):
        token_response = self.credential.get_token("https://storage.azure.com/.default")

        return (token_response.token, token_response.expires_on)

class CustomTokenCredentialSeconday(object):
    def __init__(self,token,expires_on):
        self.token = token
        self.expires_on = expires_on

    def get_token(self, *scopes, **kwargs):
        return AccessToken(self.token, self.expires_on)

token,expires_on = CustomTokenCredential().get_token()
print(token)
print(expires_on)

from datalakesurfer.format_detector import FormatDetector
f = FormatDetector(account_name="adlssynapseeus01",
    file_system_name="datacontainer",
    directory_path="salesorder",
    token=token,
    expires_on=expires_on).detect_format()
print(f)

# â†’ {'status': 'success', 'format': 'delta'}

ðŸ§ Core Concepts

Format Detectors: Identify dataset format (iceberg, delta, parquet).
Schema Retrievers: Extract a normalized schema regardless of source format.
Partition Detectors: Identify partitioning and list partition columns.
Models: All incoming parameters validated by Pydantic for correctness.

ðŸ“š Usage Examples

1. Detect Format (ADLS)

from datalakesurfer.format_detector import FormatDetector
f = FormatDetector(account_name="adlssynapseeus01",
    file_system_name="iceberg-container",
    directory_path="customerdw/mydb/product",
    token=token,
    expires_on=expires_on).detect_format()
print(f)
# {'status': 'success', 'format': 'iceberg'}

from datalakesurfer.format_detector import FormatDetector
f = FormatDetector(account_name="adlssynapseeus01",
    file_system_name="datacontainer",
    directory_path="SaleParquetData",
    token=token,
    expires_on=expires_on).detect_format()
print(f)
# {'status': 'success', 'format': 'parquet'}

2. Detect Format (Fabric)

#abfss://devworkspace@onelake.dfs.fabric.microsoft.com/devlakehouse.Lakehouse/Files/salesorder
# {'status': 'success', 'format': 'delta'}

3. Detect Format (GCS)

import json
with open("/Workspace/Users/<>/fresh-replica-393006-0398d554d3fa.json", "r") as f:
    service_account_dict = json.load(f)

from datalakesurfer.gcs_format_detector import GCSFormatDetector

# {'status': 'success', 'format': 'delta'}

f = GCSFormatDetector(service_account_info=service_account_dict,
    file_system_name="storagebucket0001",
    directory_path="ParquetDataSource").detect_format()
print(f)
# {'status': 'success', 'format': 'parquet'}
