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.
ReadonlyentityNone while the source is unset
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
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)
The data space's name: the last segment of its path
The entity's name: the last segment of its path; none while unset
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 relation's one expression, which the emitter writes; the source must be set
The type discriminator, e.g. filter
The entity and the data space, by name; the data space alone while unset. Both are known before the engine types the source.
The description without the values users typed, which may be sensitive, for logs and telemetry. By default the description, which has none.
No query has been applied from its editor yet
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 set and resolved to a schema. Set but not resolved, it waits
for the engine, which the editor asks as it lands (ERR_TYPING, pending
rather than a problem); a failed resolution reports the first line of
its error.
Optionalerrors: string[]A new source, with the same id, and these coordinates: what the editor applied. It is unresolved, since its columns may have changed.
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 host's editor returns, which must be the coordinates; other keys are left out.
A class of a data space, queried in the host's query builder (PLAN §11.25): its columns and the rows its filter keeps. Its model is the data space's project, its mapping and runtime its execution context's, all three the cube's. Its columns are the engine's typing of its relation.
