glassflow 2.0.6

GlassFlow Python Client SDK

GlassFlow Python SDK

The GlassFlow Python SDK provides a convenient way to interact with the GlassFlow API in your Python applications. The SDK is used to publish and consume events to your GlassFlow pipelines.

Installation

You can install the GlassFlow Python SDK using pip:

pip install glassflow

Data Operations

• publish - Publish a new event into the pipeline
• consume - Consume the transformed event from the pipeline
• consume failed - Consume the events that failed from the pipeline
• validate credentials - Validate pipeline credentials

publish

Publish a new event into the pipeline

Example Usage

from glassflow import PipelineDataSource

source = PipelineDataSource(pipeline_id="<str value", pipeline_access_token="<str token>")
data = {} # your json event
res = source.publish(request_body=data)

if res.status_code == 200:
    print("Published sucessfully")

consume

Consume the transformed event from the pipeline

Example Usage

from glassflow import PipelineDataSink

sink = PipelineDataSink(pipeline_id="<str value", pipeline_access_token="<str value>")
res = sink.consume()

if res.status_code == 200:
    print(res.json())

consume failed

If the transformation failed for any event, they are available in a failed queue. You can consume those events from the pipeline

Example Usage

from glassflow import PipelineDataSink

sink = PipelineDataSink(pipeline_id="<str value", pipeline_access_token="<str value>")
res = sink.consume_failed()

if res.status_code == 200:
    print(res.json())

validate credentials

Validate pipeline credentials (pipeline_id and pipeline_access_token) from source or sink

Example Usage

from glassflow import PipelineDataSource, errors

try:
    source = PipelineDataSource(pipeline_id="<str value", pipeline_access_token="<str value>")
    source.validate_credentials()
except errors.PipelineNotFoundError as e:
    print("Pipeline ID does not exist!")
    raise e
except errors.PipelineAccessTokenInvalidError as e:
    print("Pipeline Access Token is invalid!")
    raise e

Pipeline Management

In order to manage your pipelines with this SDK, one needs to provide the PERSONAL_ACCESS_TOKEN to the GlassFlow client.

from glassflow import GlassFlowClient

client = GlassFlowClient(personal_access_token="<your personal access token>")

Now you can perform CRUD operations on your pipelines:

• list_pipelines - Returns the list of pipelines available
• get_pipeline - Returns a pipeline object from a given pipeline ID
• create - Create a new pipeline
• delete - Delete an existing pipeline

list_pipelines

Returns information about the available pipelines. It can be restricted to a specific space by passing the space_id.

Example Usage

from glassflow import GlassFlowClient

client = GlassFlowClient(personal_access_token="<your access token>")
res = client.list_pipelines()

get_pipeline

Gets information about a pipeline from a given pipeline ID. It returns a Pipeline object which can be used manage the Pipeline.

Example Usage

from glassflow import GlassFlowClient

client = GlassFlowClient(personal_access_token="<your access token>")
pipeline = client.get_pipeline(pipeline_id="<your pipeline id>")

print("Name:", pipeline.name)

create

The Pipeline object has a create method that creates a new GlassFlow pipeline.

Example Usage

from glassflow import Pipeline

pipeline = Pipeline(
    name="<your pipeline name>",
    transformation_file="path/to/transformation.py",
    space_id="<your space id>",
    personal_access_token="<your personal access token>"
).create()

In the next example we create a pipeline with Google PubSub source and a webhook sink:

from glassflow import Pipeline

pipeline = Pipeline(
    name="<your pipeline name>",
    transformation_file="path/to/transformation.py",
    space_id="<your space id>",
    personal_access_token="<your personal access token>",
    source_kind="google_pubsub",
    source_config={
        "project_id": "<your gcp project id>",
        "subscription_id": "<your subscription id>",
        "credentials_json": "<your credentials json>"
    },
    sink_kind="webhook",
    sink_config={
        "url": "<webhook url>",
        "method": "<GET | POST | PUT | PATCH | DELETE>",
        "headers": [{"header1": "header1_value"}]
    }
).create()

delete

The Pipeline object has a delete method to delete a pipeline

Example Usage

from glassflow import Pipeline

pipeline = Pipeline(
    name="<your pipeline name>",
    transformation_file="path/to/transformation.py",
    space_id="<your space id>",
    personal_access_token="<your personal access token>"
).create()

pipeline.delete()
