What is Streams?
Streams is a blockchain data streaming and ETL service. It provides developers with a reliable, efficient, and intuitive way to stream blockchain data in real-time.
How is Streams different from QuickAlerts?
While both Streams and QuickAlerts are designed to provide real-time blockchain data, they serve different purposes and have distinct features.
QuickAlerts is primarily an alerting tool. It allows you to set up specific conditions or events on the blockchain that, when met, trigger alerts. This is particularly useful for making DeFi trading decisions, integrating real-time blockchain event-driven logic into your workflows, and more.
Streams is a data streaming service. It provides a continuous, real-time stream of blockchain data directly to your systems. This includes blocks with transactions, receipts, logs, and more. Streams also offers a unique reverse RPC approach, ensuring guaranteed data delivery. It comes with a user-friendly dashboard for managing streams, viewing basic statistics, controlling errors, and more. Additionally, Streams includes a transformation layer, allowing you to tailor the data to your specific needs before it's delivered.
What support does Streams offer?
Streams provides comprehensive support through our dedicated support team. You can reach out to us via ZenDesk for any queries or issues.
How much does Streams cost?
The cost of Streams depends on your usage, including the number of streams and the amount of data processed. The Billing and Usage section provides a clear overview of your consumption and associated costs, helping you manage your expenses effectively.
Features and Usage
How Can I Use Streams?
Users can interact with Streams via the UI on your QuickNode Dashboard or via API, allowing you to integrate, manage, and monitor Streams programmatically.
How Do I Retrieve Metrics?
Metrics are displayed on your Stream's metric tab. This page will display performance metrics about your stream including:
- Data Sent: The total amount of data sent to your Stream over a time period. Displayed in bytes, transactions, and number of webhook requests.
- Throughput: The amount of data that can be sent to your Stream over a given time period
- Latency: The amount of time it takes for your Stream data to be delivered
- Error: The number of errors or retries over a time period
This data can be filtered over a certain time period (e.g., last 15 mins, last hour, day, etc.)
What Do Logs Provide?
Logs provide insight into your Streams operations. If you incur an error, such as a 404 (due to an incorrect Webhook, S3), it will be displayed here. You will also receive warning messages such as retries.
How Do I Modify the Dataset of an Existing Stream?
You cannot update the Dataset (e.g., block). If you need another dataset type, you will need to create another stream.
How Do I Modify an Existing Active Stream?
Click the toggle button in the upper-right corner of your specific Stream from Active to Paused. Stream configurations that can be updated include:
- Data range (stream start and end)
- Payload details (enable compression and modify batch size)
- Destination details (reconfigure your destination URL. Note the new URL can only be updated on the same type of destination)
- Stream retries (set Stream retry handling, including a retry wait period (e.g., 2 seconds) and pause the Stream after a set amount of retries)
- Security (rotate authentication tokens to new ones in the event your API URL may be compromised)
Reorg Handling
