Module ops 

Store operations as sans-IO jobs, shared by the sync, async and JavaScript drivers.

Structs

ScanJob

A job returning quads matching a SQL WHERE clause, with batched term resolution.

Functions

clear_graph_job

Removes all quads of a graph (keeps the graph name).

clear_inferences_job

Removes every materialized inference.

clear_inferences_of_job

Removes the inferences of one producer, keeping what other producers also derived.

clear_job

Removes everything.

contains_job

contains_named_graph_job

encode_term

Helper used by drivers: encodes a term to its id without I/O.

inference_producers_job

The names of the producers that derived a quad (empty when it is not inferred). The default graph matches the graph-0 conclusions every producer writes.

insert_job

Atomically inserts quads; returns how many were new.

insert_named_graph_job

Adds a named graph; returns whether it was new.

insert_request

Insert statements for a chunk (bulk loading).

is_empty_job

len_job

materialize_job

Recomputes the OWL 2 RL materialization (quads_inf): discards previous inferences, then runs rule rounds (one atomic request each, i.e. one D1 batch) until a round infers nothing. Returns the number of inferred triples. Rounds are not one transaction: readers may see a partial materialization while it runs.

named_graphs_job

Lists named graphs.

neighbourhood_job

Quads whose subject (or, with incoming, object) is one of nodes, optionally restricted to some predicates and to the default graph: one neighbourhood hop for bounded prefetches.

open_job

Creates the schema, then loads statistics.

optimize_job

Recomputes and reloads statistics.

remove_job

Atomically removes quads; returns how many were present.

remove_named_graph_job

Removes a named graph and its quads; returns whether it existed.

scan_job

quads_for_pattern as a job. graph_name = None matches every graph, default included.

schema_refresh_for

The statements that rebuild the derived schema caches inside a write’s own request: tbox_closure when a schema axiom changed, the shape index when a SHACL triple did.

shape_index_job

Reads the compiled shape index.

stats_job

Loads statistics only.
