Logic Nodes
Logic nodes process and transform data within your workflows. They handle calculations, filtering, conditional logic, data preparation, and other transformations needed to create actionable outputs or drive further workflow steps.
| Node Name | Description |
|---|---|
| Advanced Function | Execute custom or prebuilt formulas to transform workflow data, using mathematical, logical, label-based, and time-series functions |
| Associate or Split Payload | Link incoming payloads to the correct UID based on a specified JSON key, or split an array of objects into individual payloads for separate processing |

| Conditional filter | Control whether a payload continues through the workflow based on specific conditions applied to a JSON key’s value (e.g., equals, greater than, less than, not equal) or the presence/absence of the key. |
| Count Value | Counts the number of times one or more specified JSON keys contain defined values, based on your criteria |
| Count value by time | Counts the occurrences of a specified JSON key within a defined time window, optionally filtered by another JSON key. Useful for tracking event frequency over time |
| Data Repository | Stores payload data for a defined retention period, with options to treat UID or timestamp as unique so only the latest value is stored for each. Columns are defined by JSON keys with specified data types |
| Data summary | Calculate a chosen metric for nominated JSON keys, by UID or by UIDs with matching label values, for each specified time interval. |

FAQs
Q: Are these all the nodes available in Rayven?
Yes, this list is complete and includes all current nodes as of the latest platform update.
Q: Where can I find configuration details for each node?
Each node has its own dedicated page in the Nodes Reference Guide section, with detailed configuration steps and examples.
Q: Do all nodes work in every application?
Yes, but their usefulness depends on your app’s design and data sources. Some nodes are only relevant in specific integration or display scenarios.
Q: Can I use multiple nodes from different categories in the same workflow?
Yes. Workflows often combine connector, logic, AI, and frontend nodes to handle different stages of data processing, visualisation, and automation.
Q: How do I know if a node is suitable for real-time or historical data?
The suitability depends on the node type and your workflow design. All nodes support real-time data, and many frontend nodes also support historical data where it makes sense—such as charts, tables, and other analytical widgets. Check each node’s dedicated reference page for details on data handling and update behaviour.
