Coming from KNIME

KNIME users feel at home quickly: nodes on a canvas, connected by ports, each with a status you can read at a glance. The differences are in how Daedalus handles variables, loops and reusable pieces, and that you never configure a node in a pop-up dialog.

How KNIME ideas map

In KNIME	In Daedalus
Workflow	A workflow on the canvas, saved in a project folder on your machine.
Node repository	The add-node menu (right-click the canvas) and the `⌘K` palette. KNIME node names work.
Configure dialog	The Attributes panel on the right shows the selected node's settings. No dialog to open and close.
Execute, node status lights	Run the workflow from the toolbar. Each node's badge says whether its output is up to date or needs a re-run.
Output port table, Node Monitor	Select a node and its output shows in the dock under the canvas: Data, Metadata, and Map, Chart or Report on the nodes that draw them.
Metanodes and components	Named functions: a group of nodes that collapses into one box with its own inputs and outputs.
Loop Start / Loop End pairs	A loop is one frame drawn around the nodes. It runs them once per row or file of a table, or repeats until done.
Flow variables	No flow variables. Wire a one-row table into a node's parameter input instead.
Annotations	Comment regions (toolbar ⋯ → Draw → Region) and per-node notes.
KNIME Hub schedules and deployments	Cloud runs run a project on a schedule. A read-only share link shows someone your workflow.

KNIME names in Daedalus

The most-used KNIME names and what to reach for here. You can type any of them into the add-node menu or the ⌘K palette: the matching node shows a chip with the KNIME name, so you learn the Daedalus name as you go. Where two nodes are listed, the first is the closest match.

Not in Daedalus yet

KNIME has a much larger node repository than Daedalus. The biggest gaps are machine-learning learners and predictors, statistical tests, widgets and file management. When you type one of these names, the menu shows the hint below instead of a node.

KNIME name	What to do instead
Decision Tree Learner, Random Forest Learner, k-Means, Logistic Regression Learner	No built-in ML models yet; ask Code Gen to write one in Python
PMML Writer, PMML Reader, Model Writer, Model Reader	No PMML or model files; not supported
Single Selection Widget, String Widget, Refresh Button Widget	No interactive widgets or dashboards yet
String Configuration, Integer Configuration	No configuration dialogs; wire values from a Constant Table
Independent groups t-test, One-way ANOVA, Kruskal-Wallis Test	No statistical tests yet; ask Code Gen to write one in Python
Try (Data Ports), Catch Errors (Data Ports)	No try/catch; a failing node stops its branch. Inside a Loop, turn on Continue on error to skip failing items
Create Folder, Delete Files/Folders, Decompress Files	No file-management nodes yet; manage files outside Daedalus
XPath, XML to JSON	Read .xml files with XML Reader and set its Record path; for XML text in a column, use a Code Gen node
Microsoft SQL Server Connector, Oracle Connector	Only PostgreSQL, MySQL, SQLite and Snowflake are supported
DB Updater, DB Merger, DB Row Deleter	Not supported; only create, replace and append writes exist
Container Input (Table), Container Input (JSON)	Workflows cannot be called as services yet
SARIMA Learner (Labs)	Forecast (exponential smoothing or seasonal naive); for SARIMA itself, ask Code Gen to write it in Python
Global Moran's I, Local Moran's I	No spatial autocorrelation stats yet; try Code Gen

Tips for KNIME users

Type the KNIME name. GroupBy finds Aggregate, Joiner finds Join and Column Filter finds Select Columns, each with a KNIME: chip in the add-node menu and the ⌘K palette.
Replace flow variables with a parameter table. Put the value in a Constant Table and wire it into the node's parameter input; Filter, Add Column and file names can all read from it.
Loops have no start and end nodes. Select the nodes to repeat and draw a loop around them (toolbar ⋯ → Draw → Loop), then wire the table of items into it.
Turn a metanode into a named function the same way: select the nodes and draw a named function around them. It collapses to one box you can run on its own.
Outputs are cached for you. There is no Cache node and no Reset: Run re-runs only what changed, and the badges show what is stale.
