ReadonlycolumnUnknown keys of the saved schema snapshot's columns, by column name. They stay with the columns of that name when the source is resolved again.
ReadonlydatabaseThe path of the Database element
ReadonlyidUnique within the query and shown to users, e.g. filter101
ReadonlykeyAssigned at construction from a monotonic sequence: the node's identity for change detection
ReadonlyrestThe keys of the node's saved JSON that this version does not know, kept so a re-save writes them back (PLAN §10.3); edits keep them too
ReadonlyschemaThe database schema the table is in
Whether edits may change which nodes feed this one. Not for a node whose port semantics are unknown, such as an Unknown node.
Whether the node takes rows by their order, as a Limit does: the emitter then writes its input's order as a sort just before it (PLAN §11.4)
Labels for the input ports, shown on the edges that feed them
The named input slots, in order: none for a source, one for a unary transform, two for a binary one
The type discriminator, e.g. filter
The connection is left out on purpose: the database path is long
The description without the values users typed, which may be sensitive, for logs and telemetry. By default the description, which has none.
Whether the node has none of the settings it needs yet, e.g. a Join with no key pair: the canvas shows it as not set, not by its description
The order the node's rows come in, from its inputs' orders in port order
(undefined where unknown), for computeRowOrders (PLAN §11.4). By
default no order, as from a source or a join: a node that keeps its
input's order says so, so a new node never claims an order on columns it
may not have.
Valid once resolved to a schema. A failed resolution reports the first line of its error, as the engine gave it.
Optionalerrors: string[]A new source, with the same id and coordinates, and this resolution
The node to keep once its two inputs swap ports: by default this node. A node whose settings name its inputs by side, such as a Join's key columns, returns a new node (same id) with those settings swapped too.
StaticfromBuilds an unresolved source from what the source picker returns, which must be the table's coordinates.
A table of a relational database, read through the model's Database element
