zipher-sdk 0.4.1

Python SDK for programmatic access to the Zipher API

Zipher SDK

The Zipher SDK is a Python library for interacting with Zipher's APIs.

• Package Installation
• Granting access to Zipher
• Usage

Package Installation

You can install the Zipher SDK using pip:

pip install zipher-sdk

Providing Zipher with access to Databricks workspace

After installing zipher-sdk package a cli tool to automatically create all necessary resources for Zipher is available.

Setting up credentials

You need to provide credentials that will be used to create all necessary resources and permissions for Zipher.

Here are ways to set up credentials:

• .databrickscfg config (cli tool supports profile choice as an argument)
• ZIPHER_DATABRICKS_HOST and ZIPHER_DATABRICKS_TOKEN or ZIPHER_DATABRICKS_CLIENT_ID, ZIPHER_DATABRICKS_CLIENT_SECRET environment variables
• providing credentials as arguments to cli tool

Cli tool usage examples

Providing Zipher with access to a list of jobs

zipher setup --jobs-list 12345678,87654321,12344321,21436587

Providing Zipher with access to n jobs from the workspace

zipher setup --max-jobs 50

Providing Zipher with readonly access to a list of jobs

zipher setup --readonly --jobs-list 12345678,87654321,12344321,21436587

SDK Usage

Here are some basic examples of how you can use the Zipher SDK to optimize your databricks clusters using Zipher's ML-powered optimization engine:

Update Existing Configuration

You can update an existing configuration by initializing a zipher Client and sending a JSON payload to the update_existing_conf function. Here's how you can do it:

from zipher import Client

client = Client(customer_id="my_customer_id")  # assuming the zipher API key is stored in ZIPHER_API_KEY environment variable

# Your existing cluster config:
config_payload = {
    "new_cluster": {
        "autoscale": {
            "min_workers": 1,
            "max_workers": 30
        },
        "cluster_name": "my-cluster",
        "spark_version": "10.4.x-scala2.12",
        "spark_conf": {
            "spark.driver.maxResultSize": "4g"
        },
        "aws_attributes": {
            "first_on_demand": 0,
            "availability": "SPOT",
            "zone_id": "auto",
            "spot_bid_price_percent": 100,
            "ebs_volume_count": 0
        },
        "node_type_id": "rd-fleet.2xlarge",
        "driver_node_type_id": "rd-fleet.xlarge",
        "spark_env_vars": {},
        "enable_elastic_disk": "false"
    }
}

# Update configuration
optimized_cluster = client.update_existing_conf(job_id="my-job-id", existing_conf=config_payload)

# Continue with sending the optimized configuration to Databricks via the Databricks python SDK, Airflow operator, etc.

Update Existing Multiple Tasks Configuration

You can update multiple databricks tasks by initializing a zipher Client and sending a JSON representing a list of dbx SubmitTask objects to the get_optimized_tasks function.

from zipher import Client

client = Client(customer_id="my_customer_id")  # assuming the zipher API key is stored in ZIPHER_API_KEY environment variable

tasks_to_optimize = [
    {
        "task_key": "task_1",
        "description": "Test notebook task",
        "notebook_task": {
            "notebook_path": "/path/to/your/notebook",
            "base_parameters": {
                "param1": "value1"
            }
        },
        "new_cluster": {
            "spark_version": "14.3.x-scala2.12",
            "node_type_id": "m6id.large",
            "driver_node_type_id": "m6id.large",
            "num_workers": 2,
            "aws_attributes": {
                "first_on_demand": 0,
                "availability": "SPOT",
                "zone_id": "auto",
                "spot_bid_price_percent": 100,
                "ebs_volume_count": 0
            },
            "spark_conf": {
                "spark.driver.maxResultSize": "4g"
            }
        }
    },
    {
        "task_key": "task_2",
        "description": "Test Python task",
        "spark_python_task": {
            "python_file": "/path/to/your/python_file.py",
        },
        "new_cluster": {
            "spark_version": "14.3.x-scala2.12",
            "node_type_id": "m6id.large",
            "driver_node_type_id": "m6id.large",
            "num_workers": 2,
            "spark_conf": {
                "spark.driver.maxResultSize": "4g"
            }
        },
        "timeout_seconds": 3600,
        "depends_on": [
            {
                "task_key": "task_1"
            }
        ]
    }
]

# Update tasks
optimized_tasks = client.get_optimized_tasks(job_id="my-job-id", tasks=tasks_to_optimize)

# Continue with sending the optimized tasks to Databricks via the Databricks python SDK, Airflow operator, etc.
