Data Sinks

A Data Sink in Canso is a reference to where processed data is stored. Data Sinks can be used by multiple Batch and Streaming features to save their outputs. Currently, Canso supports two types of data sinks: S3 for offline storage and Redis for online storage.

Introduction

Data Sinks provide a standardized way to store processed data, enabling:

• Efficient storage and retrieval of processed data.

• Reusability across different batch and streaming features.

• Simplified handling of data storage configurations for Data Scientists.

• Consistent methods for saving feature and pre-processing table outputs.

Data Sink Types

Offline Data Sink Attributes (S3)

These attributes define how processed data is stored and accessed in Data Sinks for offline storage.

Attribute	Description	Example
name	Unique Name of the data sink	processed_sales_orders
description	Description of what the data sink contains	Processed sales orders stored for analysis
owner	Team that owns the data sink	['[e-mail]', '[e-mail]']
bucket	Bucket Name	mycompany_processed_data
leading_key	Fixed Key Component	processed_txns/users
file_type	File Type	CSV, PARQUET
metadata	Additional metadata about the offline sink	{"output_mode": "append", "processing_time": "120 seconds", "output_partitions": 20}

Online Data Sink Attributes (Redis)

These attributes define the configuration and usage of sink for low-latency retrieval.

Attribute	Description	Example
name	Unique Name of the data sink	user_session_data
description	Description of what the data source contains	Real-time user session data for quick access
owner	Team that owns the data source	['[e-mail]', '[e-mail]']
host	Redis Host	redis://192.168.1.123:6379
metadata	Additional metadata about the online sink	{"output_mode": "append", "processing_time": "120 seconds", "output_partitions": 20}

Example object of Sinks

• S3 Sink

• Redis Sink

Working with Data Sinks

Once a Data Sink is defined, it can be:

• Registered for reusability across different teams.

• Referenced by Batch and Streaming features to save their outputs.
