Computes PageRank over a consistent snapshot. Tunable damping (default 0.85), iteration bound (default 20), and convergence tolerance (default 1e-6); the response reports how many iterations actually ran. Optional personalization seeds steer both teleport and dangling mass toward weighted nodes, and the response flags personalized: true. Results are deterministic for a fixed graph state. Accepts an optional snapshot budget and as_of for time travel.

Analytics commands compute over a consistent snapshot of the visible graph and return a complete result payload in one response. They accept optional snapshot budgets and an as_of timestamp for time travel; results are deterministic for a fixed graph state.

Examples

Compute PageRank importance scores.

Parameters

Name	Type	Required	Description
as_of	integer	no	Optional timestamp in microseconds. Reads the graph state visible at that instant.
budget	GraphAnalyticsBudget	no	Optional snapshot size bounds. Defaults to the engine limits.
damping	number	no	Optional damping factor. Defaults to 0.85.
graph	string	yes	Graph name.
max_iterations	integer	no	Optional iteration bound. Defaults to 20.
personalization	object	no	Optional seed weights (node id to weight). When present, both teleport and dangling mass follow the seeds.
tolerance	number	no	Optional convergence tolerance. Defaults to 1e-6.

Plus the optional scope: branch and space (default to the session branch and the "default" space).

Returns

AnalyticsResult<GraphPagerankData>.
